Subject: Input: sparse-keymap - report scancodes with key events
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f3cf5c4fedbe13880cd80a9fa1aebae79ebef20e;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

Input: sparse-keymap - report scancodes with key events

Scancodes are useful debugging aids when incorrect keycodes
are being sent, as is common with laptop hotkeys.
