[PATCH] video: fbdev: arkfb: Remove the unused function dac_read_reg()

From: Jiapeng Chong
Date: Wed Sep 14 2022 - 06:24:15 EST


The function dac_read_reg() is defined in the arkfb.c file, but not
called elsewhere, so delete this unused function.

drivers/video/fbdev/arkfb.c:322:18: warning: unused function 'dac_read_reg'.
