[bug report] Merge branch 'for-linux-next' of git://anongit.freedesktop.org/drm/drm-misc

[Dan Carpenter]

Hello Stephen Rothwell,

The patch 23b727d76bda: "Merge branch 'for-linux-next' of
git://anongit.freedesktop.org/drm/drm-misc" from Nov 17, 2022, leads
to the following Smatch static checker warning:

	drivers/gpu/drm/vc4/vc4_hdmi.c:351 vc4_hdmi_reset_link()
	error: uninitialized symbol 'vc4_hdmi'.

drivers/gpu/drm/vc4/vc4_hdmi.c
    346 
    347         crtc_state = crtc->state;
    348         if (!crtc_state->active)
    349                 return 0;
    350 
--> 351         mutex_lock(&vc4_hdmi->mutex);
                           ^^^^^^^^^
This locking

    352 
    353         vc4_hdmi = connector_to_vc4_hdmi(connector);
                ^^^^^^^^^^
needs to be done after this assignment.  But this is only in linux-next
so presumably it's a temporary thing.

    354         if (!vc4_hdmi_supports_scrambling(vc4_hdmi)) {
    355                 mutex_unlock(&vc4_hdmi->mutex);
    356                 return 0;
    357         }
    358 
    359         scrambling_needed = vc4_hdmi_mode_needs_scrambling(&vc4_hdmi->saved_adjusted_mode,
    360                                                            vc4_hdmi->output_bpc,
