Subject: [Intel-gfx] [PATCH] drm/i915/display: Bitwise or the conversion colour specifier together
Date: Wed, 23 Dec 2020 10:39:17 +0000	[thread overview]
Message-ID: <20201223103917.14687-1-chris@chris-wilson.co.uk> (raw)

drivers/gpu/drm/i915/display/intel_dp.c:6922 intel_dp_update_420() warn: should this be a bitwise op?
drivers/gpu/drm/i915/display/intel_dp.c:6922 intel_dp_update_420() warn: should this be a bitwise op?
drivers/gpu/drm/i915/display/intel_dp.c:6923 intel_dp_update_420() warn: should this be a bitwise op?

Inside drm_dp_downstream_rgb_to_ycbcr_conversion(), that paramter
'color_spc' is used as return port_cap[3] & color_spc, implying that it
is indeed a mask and not a boolean value.

Fixes: 522508b665df ("drm/i915/display: Let PCON convert from RGB to YCbCr if it can")
