USB: apple-mfi-fastcharge: fix reference leak in apple_mfi_fc_set_property

2020-11-06T11:06:58+00:00

pm_runtime_get_sync() will increment pm usage at first and it
will resume the device later. If runtime of the device has
error or device is in inaccessible state(or other error state),
resume operation will fail. If we do not call put operation to
decrease the reference, the result is that this device cannot
enter the idle state and always stay busy or other non-idle
state.

USB: apple-mfi-fastcharge: don't probe unhandled devices

2020-10-28T12:25:01+00:00

From: Bastien Nocera 

Contrary to the comment above the id table, we didn't implement a match
function. This meant that every single Apple device that was already
plugged in to the computer would have its device driver reprobed
when the apple-mfi-fastcharge driver was loaded, eg. the SD card reader
could be reprobed when the apple-mfi-fastcharge after pivoting root
during boot up and the module became available.

Make sure that the driver probe isn't being run for unsupported
devices by adding a match function that checks the product ID, in
addition to the id_table checking the vendor ID.

USB: legousbtower: use usb_control_msg_recv()

2020-09-25T14:33:59+00:00

The usb_control_msg_recv() function can handle data on the stack, as
well as properly detecting short reads, so move to use that function
instead of the older usb_control_msg() call.  This ends up removing a
lot of extra lines in the driver.

v2: change API of usb_control_msg_send()

usb/misc: usb3503: Use pm_ptr() macro

2020-09-04T14:53:57+00:00

Use the newly introduced pm_ptr() macro, and mark the suspend/resume
functions __maybe_unused. These functions can then be moved outside the
CONFIG_PM_SUSPEND block, and the compiler can then process them and
detect build failures independently of the config. If unused, they will
simply be discarded by the compiler.
