linux-next: manual merge of the drm tree with Linus' tree

[Stephen Rothwell]

Hi Dave,

Today's linux-next merge of the drm tree got a conflict in
drivers/gpu/drm/drm_crtc_helper.c between commit ba6f58260665
("drm/crtc-helper: skip locking checks in panicking path") from Linus'
tree and commits 6e9f798d91c5 ("drm: Split connection_mutex out of
mode_config.mutex (v3)") and 51fd371bbaf9 ("drm: convert crtc and
connection_mutex to ww_mutex (v5)") from the drm tree.

I fixed it up (not sure if entirely correctly - see below) and can
carry the fix as necessary (no action is required).
