Subject: staging: sm750fb: Remove unused function
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2ffbc9c6aa2c36cbdc584ef9669b9ef97c1283c1;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

staging: sm750fb: Remove unused function

This patch removes the unused hw712_fillrect function. This patch fixes
the following sparse warning:-

drivers/staging/sm750fb/sm750_accel.c:95:5: warning: symbol 'hw712_fillrect' was not declared. Should it be static?
