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.
