regulator: s2mpa01: Fix inconsistent indenting

2017-03-13T16:46:47+00:00

Broken indenting makes code more difficult to read and brings
confusion. Fix warning reported by Smatch:
	s2mpa01.c:362 s2mpa01_pmic_probe() warn: inconsistent indenting

regulator: s2mpa01: Constify regulator_ops

2017-03-13T16:46:28+00:00

Static struct regulator_ops is not modified so can be made const for
code safeness.

regulator: s2mpa01: reduce stack size for probe function

2017-01-26T11:21:43+00:00

In some rare configurations we can run into rather high kernel stack
consumption:

drivers/regulator/s2mpa01.c:397:1: error: the frame size of 1536 bytes is larger than 1152 bytes [-Werror=frame-larger-than=]

This is probably harmless since it happens only in the probe function,
but there is also a relatively simple workaround, moving the regulator
match data into the device specific structure.

As a small downside, we waste a little memory at runtime. An alternative
approach would free the array at the end of the probe function, which in
turn is a little more complicated.

Merge tag 'driver-core-3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core

2014-12-15T00:10:09+00:00

Pull driver core update from Greg KH:
 "Here's the set of driver core patches for 3.19-rc1.

  They are dominated by the removal of the .owner field in platform
  drivers.  They touch a lot of files, but they are "simple" changes,
  just removing a line in a structure.

  Other than that, a few minor driver core and debugfs changes.  There
  are some ath9k patches coming in through this tree that have been
  acked by the wireless maintainers as they relied on the debugfs
  changes.

  Everything has been in linux-next for a while"

regulator: s2mpa01: zero-initialize regulator match table array

2014-11-03T15:56:16+00:00

The struct of_regulator_match rmatch[] is declared as a non-static local
variable so the structure members are not auto-initialized.

Initialize the array at declaration time to avoid the structure members
values to be indeterminate and have sane defaults instead.

regulator: s2mpa01: Optimize the regulator description macro

2014-08-16T21:51:16+00:00

This patch makes the regulator description macro take minimum and
steps voltage as parameter. In this way many repeated macros can be
removed. Now these macros are repeated only if the the LDO/BUCK ctrl
registers have non-linear positions. The good thing is these ctrl registers
are mostly linear so they are not passed as parameters.

This patch reduces the code size and also allow easy addition of more
s2mpxxx PMIC drivers which differs a lot in minimum/step voltages.
