Hi all,
FIXME: Add owner of second tree to To:
Add author(s)/SOB of conflicting commits.
Today's linux-next merge of the drm-msm tree got conflicts in:
drivers/gpu/drm/msm/disp/dpu1/dpu_kms.c
drivers/gpu/drm/msm/disp/mdp4/mdp4_kms.c
drivers/gpu/drm/msm/disp/mdp5/mdp5_kms.c
drivers/gpu/drm/msm/msm_drv.c
between commits:
01790d5e372f ("drm/msm: Convert to platform remove callback returning void")
cd61a76c210a ("drm/msm: dynamically allocate the drm-msm_gem shrinker")
from the mm, drm trees and commits:
283add3e6405 ("drm/msm: remove shutdown callback from msm_platform_driver")
506efcba3129 ("drm/msm: carve out KMS code from msm_drv.c")
from the drm-msm 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.

Stephen Rothwell
