| * bus: Make remove callback return voidUwe Kleine-König2021-07-211-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver core ignores the return value of this callback because there is only little it can do when a device disappears. This is the final bit of a long lasting cleanup quest where several buses were converted to also return void from their remove callback. Additionally some resource leaks were fixed that were caused by drivers returning an error code in the expectation that the driver won't go away. With struct bus_type::remove returning void it's prevented that newly implemented buses return an ignored error code and so don't anticipate wrong expectations for driver authors.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After commit 6827ca573c03 ("memstick: rtsx_usb_ms: Support runtime power management"), removing module rtsx_usb_ms will be stuck. The deadlock is caused by powering on and powering off at the same time, the former one is when memstick_check() is flushed, and the later is called by memstick_remove_host(). Soe let's skip allocating card to prevent this issue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Drivers using legacy PM have to manage PCI states and device's PM states themselves. They also need to take care of configuration registers. With improved and powerful support of generic PM, PCI Core takes care of above mentioned, device-independent, jobs. This driver makes use of PCI helper functions like pci_save/restore_state(), pci_enable/disable_device(), pci_set_power_state() and pci_set_master() to do required operations. In generic mode, they are no longer needed. Change function parameter in both .suspend() and .resume() to "struct device*" type. Use to_pci_dev() and dev_get_drvdata() to get "struct pci_dev*" variable and drv data. Compile-tested only.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using uninitialized_var() is dangerous as it papers over real bugs[1] (or can in the future), and suppresses unrelated compiler warnings (e.g. "unused variable"). If the compiler thinks it is uninitialized, either simply initialize the variable or make compiler changes. In preparation for removing[2] the[3] macro[4], remove all remaining needless uses with the following script: git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \ xargs perl -pi -e \ 's/\buninitialized_var\(([^\)]+)\)/\1/g; s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;' drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid pathological white-space.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | mmiowb() is now implied by spin_unlock() on architectures that require it, so there is no reason to call it from driver code. This patch was generated using coccinelle: @mmiowb@ @@ - mmiowb(); and invoked as: $ for d in drivers include/linux/qed sound; do \ spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation. If you've ended up bisecting to this commit, you can reintroduce the mmiowb() calls using wmb() instead, which should restore the old behaviour on all architectures other than some esoteric ia64 systems.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to let host's parent device, rtsx_usb, to use USB remote wake up signaling to do card detection, it needs to be suspended. Hence it's necessary to add runtime PM support for the memstick host. To keep memstick host stays suspended when it's not in use, convert the card detection function from kthread to delayed_work, which can be scheduled when the host is resumed and can be canceled when the host is suspended. Put the device to suspend when there's no card and the power mode is MEMSTICK_POWER_OFF.
