hid: lenovo: Resend all settings on reset_resume for compact keyboards

Browse source

commit 2f2bd7cbd1 upstream.

The USB Compact Keyboard variant requires a reset_resume function to
restore keyboard configuration after a suspend in some situations. Move
configuration normally done on probe to lenovo_features_set_cptkbd(), then
recycle this for use on reset_resume.

Without, the keyboard and driver would end up in an inconsistent state,
breaking middle-button scrolling amongst other problems, and twiddling
sysfs values wouldn't help as the middle-button mode won't be set until
the driver is reloaded.

Tested on a USB and Bluetooth Thinkpad Compact Keyboard.
