[PATCH v1 00/12] HID: cp2112: Cleanups and refactorings

[Andy Shevchenko]

After I updated GPIO library for the case Benjamin has with CP2112,
I have a brief look into the CP2112 driver itself.

>From GPIO perspective it has two main (maitenance) issues:
- usage of ->to_irq() with IRQ chip present;
- having IRQ chip not immutable.

Besides that there are plenty small cleanups here and there.
Hence this series.

Compile tested only.

Andy Shevchenko (12):
  lib/string_choices: Add str_write_read() helper
  HID: cp2112: Use str_write_read() and str_read_write()
  HID: cp2112: Make irq_chip immutable
  HID: cp2112: Switch to for_each_set_bit() to simplify the code
  HID: cp2112: Don't call ->to_irq() explicitly
  HID: cp2112: Remove dead code
  HID: cp2112: Define maximum GPIO constant and use it
  HID: cp2112: Define all GPIO mask and use it
  HID: cp2112: Use BIT() in GPIO setter and getter
  HID: cp2112: Use sysfs_emit() to instead of scnprintf()
  HID: cp2112: Convert to DEVICE_ATTR_RW()
  HID: cp2112: Use octal permissions
