Subject: [PATCH AUTOSEL 4.9 040/141] drm/gma500: remove set but not used variable 'is_hdmi','is_crt'

From: zhengbin <zhengbin13@...wei.com>

[ Upstream commit 834c43a97f341d319aa7b74099bbce2c4e75bc72 ]

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

drivers/gpu/drm/gma500/cdv_intel_display.c: In function cdv_intel_crtc_mode_set:
drivers/gpu/drm/gma500/cdv_intel_display.c:594:7: warning: variable is_hdmi set but not used [-Wunused-but-set-variable]
drivers/gpu/drm/gma500/cdv_intel_display.c: In function cdv_intel_crtc_mode_set:
drivers/gpu/drm/gma500/cdv_intel_display.c:593:7: warning: variable is_crt set but not used [-Wunused-but-set-variable]

They are not used since commit acd7ef927e06 ("gma500:
Update the Cedarview clock handling")
