Subject: [Intel-gfx] [PATCH 1/2] drm/i915/dp: Do not set master_trans bit in bitmak if INVALID_TRANSCODER
Date: Wed, 22 Jan 2020 16:24:14 -0800	[thread overview]
Message-ID: <20200123002415.31478-1-manasi.d.navare@intel.com> (raw)

In the port sync mode, for the master crtc, the master_transcoder is INVALID.
In that case since its value is -1, do not set the bit in the bitmask.
