[PATCH 01/12] vt: move set_leds to keyboard.c

From: Jiri Slaby
Date: Tue Jan 05 2021 - 07:03:41 EST


set_leds and compute_shiftstate are called from a single place in vt.c.
Let's combine these two into vt_set_leds_compute_shiftstate. This allows
for making keyboard_tasklet local in the next patch.
