[bug report] drm/msm/dpu: drop dpu_encoder_phys_ops.atomic_mode_set

[Dan Carpenter <dan.carpenter@xxxxxxxxxx>]

Hello Dmitry Baryshkov,

This is a semi-automatic email about new static checker warnings.

    drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_cmd.c:746 dpu_encoder_phys_cmd_init()
    warn: variable dereferenced before check 'phys_enc->hw_intf' (see line 742)

drivers/gpu/drm/msm/disp/dpu1/dpu_encoder_phys_cmd.c
   741		phys_enc->intf_mode = INTF_MODE_CMD;
   742		phys_enc->irq[INTR_IDX_UNDERRUN] = phys_enc->hw_intf->cap->intr_underrun;
                                                   ^^^^^^^^^^^^^^^^^
The patch adds an unchecked dereference

   743	
   744		cmd_enc->stream_sel = 0;
   745	
   746		if (!phys_enc->hw_intf) {
                    ^^^^^^^^^^^^^^^^^^
Too late

   747			DPU_ERROR_CMDENC(cmd_enc, "no INTF provided\n");
   748			return ERR_PTR(-EINVAL);
