[PATCH] Input: gpio-keys: Avoid clearing twice some memory

From: Christophe JAILLET <hidden>
Date: 2021-12-29 21:27:06
Also in: linux-input, lkml
Subsystem: input (keyboard, mouse, joystick, touchscreen) drivers, the rest · Maintainers: Dmitry Torokhov, Linus Torvalds

bitmap_parselist() already clears the 'bits' bitmap, so there is no need
to clear it when it is allocated. This just wastes some cycles.
