2023-03-22drm/bridge: lt8912b: return EPROBE_DEFER if bridge is not foundMatheus Castello1-2/+2
Returns EPROBE_DEFER when of_drm_find_bridge() fails, this is consistent with what all the other DRM bridge drivers are doing and this is required since the bridge might not be there when the driver is probed and this should not be a fatal failure.

2023-01-05drm/bridge: panel: Prevent ERR_PTR DereferenceMaxime Ripard1-4/+5
Commit 5ea6b1702781 ("drm/panel: Add prepare_prev_first flag to drm_panel") introduced an access to the bridge pointer in the devm_drm_panel_bridge_add_typed() function. However, due to the unusual ERR_PTR check when getting that pointer, the pointer access is done even though the pointer might be an error pointer. Rework the function for a more traditional design that will return immediately if it gets an ERR_PTR so that we never access the pointer in that case.

The function it66121_wait_ddc_ready() would previously read the status register until "true", which means it never actually polled anything and would just read the register once. Now, it will properly wait until the DDC hardware is ready or until it reported an error. The 'busy' variable was also renamed to 'error' since these bits are set on error and not when the DDC hardware is busy. Since the DDC ready function is now working properly, the msleep(20) can be removed.

Pull drm updates from Dave Airlie: "The biggest highlight is that the accel subsystem framework is merged. Hopefully for 6.3 we will be able to line up a driver to use it. In drivers land, i915 enables DG2 support by default now, and nouveau has a big stability refactoring and initial ampere support, AMD includes new hw IP support and should build on ARM again. There is also an ofdrm driver to take over offb on platforms it's used.
