Subject[PATCH v2 00/15] staging cleanups
Date
This patch set contains more of my cleanups to the isl29028 light driver
in preparation for moving the driver out of staging. The main feature
introduced by this patch set is support for runtime power management
and autosuspend after two seconds. The rest of the patches are minor
code improvements, mostly style.

The ALS and IR portion of the sensor was tested using an ISL29028 hooked
up to a Raspberry Pi 2. In my v1 submission cover letter, I mention that
I am not able to use the proximity sensing function on my sensor. (This
is before any of my code changes.) I'm going to look into that issue
next. I suspect that it is a hardware issue on my local setup. I verified
with a visible light LED that the IRDR pin continues to be driven as
expected when a proximity reading is requested and is turned off after
two seconds of inactivity. The pin is driven the next time a proximity
reading is requested.

Changes since version 1:
- Suggestions from Jonathan Cameron
- In v1 patch #4 (#15 in this series), remove suspended flag. Added
support for runtime power management support and autosuspend.
- Dropped v1 patch #19 (remove legacy device tree binding)
- Dropped v1 patch #11 (made column alignment in isl29028_channels
consistent)
- In v1 patches #13 and #14, if there is an error, return inside
the error check.
- It was suggested to drop the v1 #2 patch that removes the enable
flag from isl29028_enable_proximity(). I think that we can apply
that patch now that the driver has runtime power management support.
- Suggestions from Dan Carpenter
- Dropped v1 patch #12 (fix comparison between signed and unsigned
integers)
