[PATCH] regulator: MAX20086: add gpio/consumer.h

[PATCH] regulator: MAX20086: add gpio/consumer.h

[Randy Dunlap]

max20086-regulator.c needs <linux/gpio/consumer.h> for an enum, some
macros, and a function prototype. (seen on ARCH=m68k)

Adding this header file fixes multiple build errors:

../drivers/regulator/max20086-regulator.c: In function 'max20086_i2c_probe':
../drivers/regulator/max20086-regulator.c:217:26: error: storage size of 'flags' isn't known
  217 |         enum gpiod_flags flags;
../drivers/regulator/max20086-regulator.c:261:27: error: 'GPIOD_OUT_HIGH' undeclared (first use in this function); did you mean 'GPIOF_INIT_HIGH'?
  261 |         flags = boot_on ? GPIOD_OUT_HIGH : GPIOD_OUT_LOW;
      |                           ^~~~~~~~~~~~~~
../drivers/regulator/max20086-regulator.c:261:44: error: 'GPIOD_OUT_LOW' undeclared (first use in this function); did you mean 'GPIOF_INIT_LOW'?

../drivers/regulator/max20086-regulator.c:217:26: warning: unused variable 'flags' [-Wunused-variable]
  217 |         enum gpiod_flags flags;

Applied to

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git for-linus

Thanks!

[1/1] regulator: MAX20086: add gpio/consumer.h
      commit: b4c18c18ebf7cf1e602af88c12ef9cb0d6e5ce51

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
