Subject[PATCH AUTOSEL 4.19 063/252] drm/gma500: remove set but not used variable 'htotal'
Date
From: zhengbin <zhengbin13@huawei.com>

[ Upstream commit dfa703b6f91818fa9f652c00e3589c104c518930 ]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/gma500/oaktrail_hdmi.c: In function htotal_calculate:
drivers/gpu/drm/gma500/oaktrail_hdmi.c:160:6: warning: variable htotal set but not used [-Wunused-but-set-variable]

It is introduced by commit 39ec748f7174 ("gma600: Enable HDMI support"),
but never used, so remove it.
