Pull follow_pfn() updates from Daniel Vetter:
"Fixes around VM_FPNMAP and follow_pfn:
- replace mm/frame_vector.c by get_user_pages in misc/habana and
drm/exynos drivers, then move that into media as it's sole user
- close race in generic_access_phys
- s390 pci ioctl fix of this series landed in 5.11 already
- properly revoke iomem mappings (/dev/mem, pci files)"
* tag 'topic/iomem-mmap-vs-gup-2021-02-22' of git://anongit.freedesktop.org/drm/drm:
PCI: Revoke mappings like devmem
PCI: Also set up legacy files only after sysfs init
sysfs: Support zapping of binary attr mmaps
resource: Move devmem revoke code to resource framework
/dev/mem: Only set filp->f_mapping
PCI: Obey iomem restrictions for procfs mmap
mm: Close race in generic_access_phys
media: videobuf2: Move frame_vector into media subsystem
mm/frame-vector: Use FOLL_LONGTERM

It's the only user. This also garbage collects the CONFIG_FRAME_VECTOR
symbol from all over the tree (well just one place, somehow omap media
driver still had this in its Kconfig, despite not using it).

This is used by media/videbuf2 for persistent dma mappings, not just
for a single dma operation and then freed again, so needs
FOLL_LONGTERM.
Unfortunately current pup_locked doesn't support FOLL_LONGTERM due to
locking issues. Rework the code to pull the pup path out from the
mmap_sem critical section as suggested by Jason.
By relying entirely on the vma checks in pin_user_pages and follow_pfn
(for vm_flags and vma_is_fsdax) we can also streamline the code a lot.
Note that pin_user_pages_fast is a safe replacement despite the
seeming lack of checking for vma->vm_flasg & (VM_IO | VM_PFNMAP). Such
ptes are marked with pte_mkspecial (which pup_fast rejects in the
fastpath), and only architectures supporting that support the
pin_user_pages_fast fastpath.

This driver can use the replacement API instead of calling
of_match_device() and then dereferencing the pointer that is returned.
This nicely avoids referencing the match table when it is undefined with
configurations where CONFIG_OF=n.

ASoC: Updates for v5.12
Another quiet release in terms of features, though several of the
drivers got quite a bit of work and there were a lot of general changes
resulting from Morimoto-san's ongoing cleanup work.
- As ever, lots of hard work by Morimoto-san cleaning up the code and
making it more consistent.
- Many improvements in the Intel drivers including a wide range of
quirks and bug fixes.
- A KUnit testsuite for the topology code.
- Support for Ingenic JZ4760(B), Intel AlderLake-P, DT configured
nVidia cards, Qualcomm lpass-rx-macro and lpass-tx-macro
- Removal of obsolete SIRF prima/atlas, Txx9 and ZTE zx drivers.

The driver core ignores the return value of the remove callback, so
don't give isa drivers the chance to provide a value.
Adapt all isa_drivers with a remove callbacks accordingly; they all
return 0 unconditionally anyhow.

Instead of an unconditional return 0, return no value. One of the two
callers ignored the return value already before.
This simplifies the next patch.

Since commit 7f03d9fefcc5 ("media: i2c: Kconfig: Make MAX9271
a module") the max9271 library is built as a module but no
MODULE_*() attributes were specified, causing a build error
due to missing license information.
ERROR: modpost: missing MODULE_LICENSE() in drivers/media/i2c/max9271.o
Fix this by adding MODULE attributes to the driver.

With the introduction of the RDACM21 camera module support in commit
a59f853b3b4b ("media: i2c: Add driver for RDACM21 camera module") the
symbols defined by the max9271 library were exported twice if multiple
users of the library were compiled in at the same time.
In example:
WARNING: modpost: drivers/media/i2c/rdacm21-camera_module:
'max9271_set_serial_link' exported twice. Previous export was in
drivers/media/i2c/rdacm20-camera_module.ko
Fix this by making the max9271 file a module and have the driver
using its functions select it.

- vblank/hblank/pixel rate/link freq control support
- supported resolution:
- 3840x2160 @ 60fps
- supported bayer order output:

The previously added modes 3264x2448 & 1632x1224 are actually
configuring the sensor for BGGR mode, this is an issue since
the mode that is exposed through V4L incorrectly is set as GRBG.
This patch fixes the issue by moving the output crop window of
internal sensor ISP uses by one row, which means that the Bayer
pattern of the output is changed.

This control is needed for imx219 driver, as the link frequency
is independent from the pixel rate in this case, and can't be

ipu3-cio2-bridge uses several features of the ACPI framework that have no
meaningful replacement when ACPI is disabled. Instead of adding #ifdefs to
the affected places, only build the bridge code if CONFIG_ACPI is enabled.

The V4L2 temporary clock helper API, was introduced
in late 2012 and, as mentioned in the documentation,
meant to be replaced by the generic clock API,
once the generic clock framework became available
on all relevant architectures.
The generic clock API is a well-established API (since a few
years now). The last few media capture drivers and sensors
using v4l2-clk have been converted to the generic clock framework.
We can now remove the v4l2-clk API.

removed the last in-tree user of this sensor. New users

so it's possible to convert the driver to use it.

The pointer to 'struct v4l2_subdev' is stored in drvdata via
v4l2_i2c_subdev_init() so there is no point of a dance like:
struct i2c_client *client = to_i2c_client(struct device *dev)
struct v4l2_subdev *sd = i2c_get_clientdata(client);
This allows to remove local variable 'client' and few pointer
dereferences.

in the v4l2_subdev_ops struct which is a pointer to const, and the only

The RDACM21 is a GMSL camera supporting 1280x1080 resolution images
developed by IMI based on an Omnivision OV10640 sensor, an Omnivision
OV490 ISP and a Maxim MAX9271 GMSL serializer.
The driver uses the max9271 library module, to maximize code reuse with
other camera module drivers using the same serializer, such as rdacm20.

The functions that add an async subdev to an async subdev notifier take
as an argument the size of the container structure they need to
allocate. This is error prone, as passing an invalid size will not be
caught by the compiler. Wrap those functions in macros that take a
container type instead of a size, and cast the returned pointer to the
desired type. The compiler will catch mistakes if the incorrect type is
passed to the macro, as the assignment types won't match.

Most -if not all- use-cases are expected to be covered by one of:
v4l2_async_notifier_add_fwnode_subdev,
v4l2_async_notifier_add_fwnode_remote_subdev or
v4l2_async_notifier_add_i2c_subdev.
We'd like to discourage drivers from using v4l2_async_notifier_add_subdev,
so rename it as __v4l2_async_notifier_add_subdev. This is
typically a good hint for drivers to avoid using the function.

Change v4l2_async_notifier_add_fwnode_remote_subdev semantics
so it allocates the struct v4l2_async_subdev pointer.
This makes the API consistent: the v4l2-async subdevice addition
functions have now a unified usage model. This model is simpler,
as it makes v4l2-async responsible for the allocation and release
of the subdevice descriptor, and no longer something the driver
has to worry about.
On the user side, the change makes the API simpler for the drivers
to use and less error-prone.

The "mode_index == ARRAY_SIZE(ov5648_modes)" check ensures that we
exited the loop via a break statement so we know that "mode" must
be valid. Delete this unnecessary NULL check.

The asd allocated with v4l2_async_notifier_add_fwnode_subdev() must be
of size max9286_asd, otherwise access to max9286_asd->source will go to
unallocated memory.

The last user for this type of match was the soc-camera/sh_mobile_csi2
driver, which was removed in v4.9. If the support is ever needed,
it can always be restored.
[Sakari Ailus: Also drop DEVNAME from debug prints recently added.]
