Subject: [PATCH 07/12] drm/msm/mdp4: Fix modifier support enabling
Date: Tue, 13 Apr 2021 11:48:58 +0200
Message-ID: <20210413094904.3736372-7-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <20210413094904.3736372-1-daniel.vetter@ffwll.ch>

Setting the cap without the modifier list is very confusing to
userspace. Fix that by listing the ones we support explicitly.

Stable backport so that userspace can rely on this working in a
reasonable way, i.e. that the cap set implies IN_FORMATS is available.
