All checks for _dpu_crtc_power_enable are not true, so the function can never return an error code. This removes the need for the function as pm_runtime functions can be used instead. v3: Separated _dpu_crtc_power_enable into _dpu_crtc_power_enable and _dpu_crtc_power_disable for clarity. v4: Removed both _dpu_crtc_power_enable and _dpu_crtc_power_disable and called pm_runtime_get_sync and pm_runtime_put_sync from all call points Reviewed-by:

Removes some checks from dpu_plane.c that will never result in an error. Subsequent variable assignments become part of the initialization wherever possible. Unused variables are removed. v3: removed additional impossible checks and called helper function _dpu_plane_get_kms() where possible. Reviewed-by:

dpu_plane_atomic_check() is a very thin wrapper around dpu_plane_sspp_atomic_check(). All it does is a NULL-check of state->fb, which is already done by drm_atomic_helper_check_plane_state(). Further, the helper sets state->visible = false when this is true. So remove dpu_plane_atomic_check() and just use dpu_plane_sspp_atomic_check() directly.

The MDSS device is created before the MSM driver attempts to bind the sub components. If any of the components return -EPROBE_DEFER the MDSS device is destroyed and tried again later. If this happens the dpu_mdss_isr interrupt created from the DPU MDSS is not freed when the MDSS device is destroyed and has a risk of triggering later and hitting a fault by accessing a mmio region that no longer exists. Even if the interrupt isn't triggered by accident when the device attempts to reprobe it would error out when it tries to re-register the interrupt so unconditionally removing it in the destroy is the right move. Switch the device managed dpu_mdss_isr to be unmanaged and add a free_irq() in the mdss destroy function. Reviewed-by:

The atomic_check is a bit too aggressive with respect to planes which leave the active area. This caused a bunch of log spew when the cursor got to the edge of the screen and stopped it from going all the way.
