Subject: [PATCH -next] drm/komeda: remove set but not used variable 'kcrtc'

From: YueHaibing <yuehaibing@...wei.com>

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

drivers/gpu/drm/arm/display/komeda/komeda_plane.c: In function komeda_plane_atomic_check:
drivers/gpu/drm/arm/display/komeda/komeda_plane.c:49:22: warning: variable kcrtc set but not used [-Wunused-but-set-variable]

It is never used since introduction in
commit 7d31b9e7a550 ("drm/komeda: Add komeda_plane/plane_helper_funcs")
