intf and wb resources are not dependent on the rm global state so need not be allocated during dpu_encoder_virt_atomic_mode_set().Move the allocation of intf and wb resources to dpu_encoder_setup_display() so that we can utilize the hw caps even during atomic_check() phase. Since dpu_encoder_setup_display() already has protection against setting invalid intf_idx and wb_idx, these checks can now be dropped as well. Fixes: e02a559a720f ("make changes to dpu_encoder to support virtual encoder")
Please adjust the Fixes tags in all three commits. I didn't notice this beforehand and Stephen has complained.
