drm/imx/dcss: Add missing of_node_put() in fail path

2022-07-20T07:12:15+00:00

In dcss_dev_create() and dcss_dev_destroy(), we should call of_node_put() in fail path or before the dcss's destroy as of_graph_get_port_by_id() has increased the refcount.

drm: imx: fix compiler warning with gcc-12

2022-06-09T16:39:44+00:00

Gcc-12 correctly warned about this code using a non-NULL pointer as a truth value: drivers/gpu/drm/imx/ipuv3-crtc.c: In function ‘ipu_crtc_disable_planes’: drivers/gpu/drm/imx/ipuv3-crtc.c:72:21: error: the comparison will always evaluate as ‘true’ for the address of ‘plane’ will never be NULL [-Werror=address] 72 | if (&ipu_crtc->plane[1] && plane == &ipu_crtc->plane[1]->base) | ^ due to the extraneous '&' address-of operator. Philipp Zabel points out that The mistake had no adverse effect since the following condition doesn't actually dereference the NULL pointer, but the intent of the code was obviously to check for it, not to take the address of the member.

drm/imx: dw_hdmi-imx: Fix bailout in error cases of probe

2022-04-04T07:37:42+00:00

In dw_hdmi_imx_probe(), if error happens after dw_hdmi_probe() returns successfully, dw_hdmi_remove() should be called where necessary as bailout.

drm/imx: imx-ldb: Check for null pointer after calling kmemdup

2022-04-04T07:37:41+00:00

As the possible failure of the allocation, kmemdup() may return NULL pointer. Therefore, it should be better to check the return value of kmemdup() and return error if fails.

drm/imx: ipuv3-plane: Remove redundant color encoding and range initialisation

2022-04-04T07:34:21+00:00

The imx KMS driver will call drm_plane_create_color_properties() with a default encoding and range values of BT601 and Limited Range, respectively. Since the initial value wasn't carried over in the state, the driver had to set it again in ipu_plane_state_reset(). However, the helpers have been adjusted to set it properly at reset, so this is not needed anymore.
