USB: iowarrior: fix up report size handling for some devices

2020-08-11T13:35:30Z

commit 17a82716587e9d7c3b246a789add490b2b5dcab6 upstream. In previous patches that added support for new iowarrior devices, the handling of the report size was not done correct. Fix that up and update the copyright date for the driver Reworked from an original patch written by Christoph Jung.

USB: sisusbvga: Change port variable from signed to unsigned

2020-04-23T13:26:17Z

Change a bunch of arguments of wrapper functions which pass signed integer to an unsigned integer which might cause undefined behaviors when sign integer overflow.

usb: usb251xb: fix regulator probe and error handling

2020-03-04T09:56:26Z

Commit 4d7201cda226 ("usb: usb251xb: add vdd supply support") didn't covered the non-DT use-case and so the regualtor_enable() call during probe will fail on those platforms. Also the commit didn't handled the error case correctly. Move devm_regulator_get() out of usb251xb_get_ofdata() to address the 1st issue. This can be done without worries because devm_regulator_get() handles the non-DT use-case too. Add devm_add_action_or_reset() to address the 2nd bug.

USB: Add driver to control USB fast charge for iOS devices

2020-02-12T19:01:55Z

iOS devices will not draw more than 500mA unless instructed to do so. Setting the charge type power supply property to "fast" tells the device to start drawing more power, using the same procedure that official "MFi" chargers would.

Add new device ids for the 28 and 28L devices. These have 4 interfaces instead of 2, but the driver binds the same, so the driver changes are minimal. Cc: Christoph Jung Cc: stable Link: https://lore.kernel.org/r/20200212040422.2991-2-gregkh@linuxfoundation.org Signed-off-by: Greg Kroah-Hartman
