Subject[PATCH] drm: fix setting of plane_mask in pan_display_atomic() function for linux-4.4
Date
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.
