Subject: [PATCH v3 1/9] drm/vc4: txp: Properly set the possible_crtcs mask
Date: Tue, 13 Apr 2021 16:54:33 +0200 [thread overview]
Message-ID: <20210413145441.483977-2-maxime@cerno.tech> (raw)
In-Reply-To: <20210413145441.483977-1-maxime@cerno.tech>
The current code does a binary OR on the possible_crtcs variable of the
TXP encoder, while we want to set it to that value instead.
Cc: <stable@vger.kernel.org> # v5.9+
Fixes: 39fcb2808376 ("drm/vc4: txp: Turn the TXP into a CRTC of its own")
Acked-by: Thomas Zimmermann <tzimmermann@suse.de>
