[PATCH v3 00/10] gpio: mockup: refactoring + documentation

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx>

These patches were part of the bigger overhaul of gpio-mockup but since
the initial idea was dropped in favor of using configfs + sysfs in the
future I thought I'd resent just the refactoring of the existing code
+ documentation patches. I think it's good to apply them since we don't
really know when the new interface will be ready (configfs needs a new
functionality - commitable items - to support mockup chip instantiation).

v1 -> v2:
- check for NULL pointer in kfree_strarray() to avoid having to always pass
  a zeroed string count when the array pointer is NULL
- collect review tags from Andy

v2 -> v3:
- add a patch increasing the number of supported device properties
- rename the arguments in kfree_strarray()

Bartosz Golaszewski (10):
  lib: string_helpers: provide kfree_strarray()
  Documentation: gpio: add documentation for gpio-mockup
  gpio: mockup: drop unneeded includes
  gpio: mockup: use KBUILD_MODNAME
  gpio: mockup: use pr_fmt()
  gpio: mockup: remove unneeded return statement
  gpio: mockup: increase the number of supported device properties
  gpio: mockup: pass the chip label as device property
  gpio: mockup: use the generic 'gpio-line-names' property
  gpio: mockup: refactor the module init function
