Seems like I should post a v4 to update the commit message of the final patch in the series, but I'm going to leave this the way it is since the end result is the same. Originally when I wrote the series I didn't know if the new regulator API changes would be accepted, so the previous patch did the most cleanup it could do with the old API. ;-) -Doug

As of commit 6eabfc018e8d ("regulator: core: Allow specifying an initial load w/ the bulk API") we can now specify the initial load in the bulk data rather than having to manually call regulator_set_load() on each regulator. Let's use it. Signed-off-by: Douglas Anderson <dianders@chromium.org> --- Changes in v3: - Update commit message to point at the git hash of the regulator change. Changes in v2: - ("Use the new regulator bulk feature to specify the load") new for v2. drivers/gpu/drm/msm/dsi/dsi_host.c | 13 +++---------- drivers/gpu/drm/msm/dsi/phy/dsi_phy.c | 13 +++---------- 2 files changed, 6 insertions(+), 20 deletions(-)
