Before accessing the u/v offset(aka, u/vbo for IPUv3) of the old plane state's relevant fb, we should make sure the fb is in YU12 or YV12 pixel format(which are the two YUV pixel formats we support only), otherwise, we are likely to trigger BUG_ON() in drm_plane_state_to_u/vbo() since the fb's pixel format is probably not YU12 or YV12.

commit e73aca5184ad9fc948ba22b4d35dce11db35bb25 upstream.

Before accessing the u/v offset(aka, u/vbo for IPUv3) of the old plane state's
relevant fb, we should make sure the fb is in YU12 or YV12 pixel format(which
are the two YUV pixel formats we support only), otherwise, we are likely to
trigger BUG_ON() in drm_plane_state_to_u/vbo() since the fb's pixel format is
probably not YU12 or YV12.

drm/imx: ipuv3-plane: Switch EBA buffer only when we don't need modeset 2016-11-10T15:38:54+00:00 Liu Ying gnuiyl@gmail.com 2016-10-10T06:50:06+00:00 d040374f3473124cadf2e44c0afd2c6ac5451c83 commit 43daa01323da37a3692cabe1579ef5c2c4372e06 upstream. We added active plane reconfiguration support by forcing a full modeset operation. So, looking at old_plane_state->fb to determine whether we need to switch EBA buffer(for hardware double buffering) in ipu_plane_atomic_set_base() or not is no more correct. Instead, we should do that only when we don't need modeset, otherwise, we initialize the two EBA buffers with the buffer address.
