Subject: [PATCH] drm: fix setting of plane_mask in pan_display_atomic() function for linux-4.4
Date: Sat, 23 May 2020 11:49:07 +0800 [thread overview]
Message-ID: <1590205747-19599-1-git-send-email-chenxb_99091@126.com> (raw)
From: Xuebing Chen <chenxb_99091@126.com>
The <include/drm/drm_crtc.h> provides drm_for_each_plane_mask macro and
plane_mask is defined as bitmask of plane indices, such as
1<<drm_plane_index(plane). This patch fixes error setting of plane_mask
in pan_display_atomic() function.
