Hi all,
Today's linux-next merge of the drm-misc tree got a conflict in:
drivers/gpu/drm/vc4/vc4_hdmi.c
between commit:
682f99b8ae88 ("drm/vc4: hdmi: Take our lock to reset the link")
from the origin tree and commits:
d218750805a3 ("drm/vc4: hdmi: Pass vc4_hdmi to vc4_hdmi_supports_scrambling()")
0a99962c0dbf ("drm/vc4: hdmi: Fix pointer dereference before check")
from the drm-misc tree.
I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging. You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.
