Commit Message

Hans de Goede Jan. 11, 2022, 10:56 a.m. UTC 
The gpio-tps68470 driver binds to a tps68470-gpio platform-device which
itself gets instantiated by a special MFD driver from
drivers/platform/x86/intel/int3472/tps68470.c

This MFD driver itself can be built as a module, so it makes no sense to
force the gpio-tps68470 driver to always be built-in.

Changes in v2:
- Fix some spelling errors in the commit msg
- Remove blank line between tps68470_gpio_driver decleration and
  module_platform_driver(tps68470_gpio_driver)
