Subject: [PATCH] drm/bridge: synopsys: dw-dp: fix signedness bug in dw_dp_video_need_vsc_sdp()
Date: Thu, 25 Dec 2025 21:44:01 +0300 [thread overview]
Message-ID: <20251225184401.414021-1-alperyasinak1@gmail.com> (raw)
Since dw_dp_video_need_vsc_sdp() returns bool, have it return false
instead of -EINVAL if state is NULL.
Fixes: 86eecc3a9c2e ("drm/bridge: synopsys: Add DW DPTX Controller support library")
