* USB: serial: mos7720: fix remote wakeupJohan Hovold2019-11-121-4/+0
| | | | | | | | | | | | | | | The driver was setting the device remote-wakeup feature during probe in violation of the USB specification (which says it should only be set just prior to suspending the device). This could potentially waste power during suspend as well as lead to spurious wakeups. Note that USB core would clear the remote-wakeup feature at first resume.

* USB: serial: mos7720: fix mos_parport refcount imbalance on error pathLin Yi2019-03-201-2/+2
| | | | | | | | | | | | | | | The write_parport_reg_nonblock() helper takes a reference to the struct mos_parport, but failed to release it in a couple of error paths after allocation failures, leading to a memory leak. Johan said that move the kref_get() and mos_parport assignment to the end of urbtrack initialisation is a better way, so move it. and mos_parport do not used until urbtrack initialisation.

* USB: serial: mos7720: use irqsave() in USB's complete callbackJohn Ogness2018-06-261-2/+3
| | | | | | | | | | | | | | The USB completion callback does not disable interrupts while acquiring the lock. We want to remove the local_irq_disable() invocation from __usb_hcd_giveback_urb() and therefore it is required for the callback handler to disable the interrupts while acquiring the lock. The callback may be invoked either in IRQ or BH context depending on the USB host controller. Use the _irqsave() variant of the locking primitives.

| | | | | | | | | | | | | | | | | Now that the SPDX tag is in all USB files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

* USB: add SPDX identifiers to all remaining files in drivers/usb/Greg Kroah-Hartman2017-11-041-0/+1
| | | | | | | | | | | | | | | | | | | | | It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

* USB: serial: make minor allocation dynamicGreg Kroah-Hartman2013-06-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | This moves the allocation of minor device numbers from a static array to be dynamic, using the idr interface. This means that you could potentially get "gaps" in a minor number range for a single USB serial device with multiple ports, but all should still work properly. We remove the 'minor' field from the usb_serial structure, as it no longer makes any sense for it (use the field in the usb_serial_port structure if you really want to know this number), and take the fact that we were overloading a number in this field to determine if we had initialized the minor numbers or not, and just use a flag variable instead. Note, we still have the limitation of 255 USB to serial devices in the system, as that is all we are registering with the TTY layer at this point in time.

They really wanted the number of the port within the device, which you had to subtract from the minor of the parent usb_serial_device structure. To clean this up, provide the real minor number of the port, and the number of the port within the serial device separately, as these numbers might not be related in the future. Bonus is that this cleans up a lot of logic in the drivers, and saves lines overall.

Lots of USB patches here, the majority being USB gadget changes and USB-serial driver cleanups, the rest being ARM build fixes / cleanups, and individual driver updates. We also finally got some chipidea fixes, which have been delayed for a number of kernel releases, as the maintainer has now reappeared.

| * USB: mos7720: always disable uart on closeJohan Hovold2013-03-251-10/+3
| | | | | | | | | | | | | | | | | | | | | | | | Always try to disable the uart on close. Since the switch to tty ports, close will be called as part of shutdown before disconnect returns. Hence there is no need to check the disconnected flag, and we can put devices in disabled states also on driver unbind.

| * USB: mos7720: remove broken get_icount and TIOCMIWAITJohan Hovold2013-03-251-55/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove broken get_icount and TIOCMIWAIT support. The driver has an icount structure but it is never been updated which makes get_icount rather pointless and causes TIOCMIWAIT to always return -EIO. Note that the TIOCMIWAIT implementation has always been broken and would not work even if icount support was added as it does not wait for the modem status to change (does not use a work queue at all).

* | TTY: add tty_port_tty_wakeup helperJiri Slaby2013-03-191-6/+2
|/ | | | | | | | | | | | It allows for cleaning up on a considerable amount of places. They did port_get, wakeup, kref_put. Now the only thing needed is to call tty_port_tty_wakeup which does exactly that. One exception is ifx6x60 where tty_wakeup was open-coded. We now call tty_wakeup properly there.

* TTY: switch tty_flip_buffer_pushJiri Slaby2013-01-161-5/+2
| | | | | | | | | | | | | | | | | | | | Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths. Now, the one where most of tty_port_tty_get gets removed: tty_flip_buffer_push. IOW we also closed all the races in drivers not using tty_port_tty_get at all yet. Also we move tty_flip_buffer_push declaration from include/linux/tty.h to include/linux/tty_flip.h to all others while we are changing it anyway.
