linux-next: build failure after merge of the regulator tree

Hi all,

After merging the regulator tree, today's linux-next build (arm multi_v7_defconfig)
failed like this:

drivers/gpu/drm/msm/dsi/dsi_host.c: In function 'dsi_host_regulator_disable':
drivers/gpu/drm/msm/dsi/dsi_host.c:330:4: error: implicit declaration of function 'regulator_set_optimum_mode' [-Werror=implicit-function-declaration]
    regulator_set_optimum_mode(s[i].consumer,
    ^

Caused by commit a689554ba6ed ("drm/msm: Initial add DSI connector
support") from the drm tree interacting with commit ae6e808f1574
("regulator: Drop temporary regulator_set_optimum_mode wrapper") from
the regulator tree.

This happens every time someone renames/changes an API :-(

I have applied the following merge fix patch.  Someone needs to make
sure Linus finds out when the latter of these two trees is merged into
his.
