Subject: [PATCH 0/4] mmc: simplify WP/CD GPIO handling

This series removes convoluted handling of inverted CD and WP lines in
SD/MMC host drivers when using GPIOs.

First patch, sent separately earlier, adds gpiod_toggle_active_low() to
switch line inversion flag in the gpiod structure. Next two patches
modify WP and CD initialization to apply all the inversions onto gpiod's
active-low flag. Final patch removes now-unused argument from init functions.

x86 allyesconfig build-tested.

Michał Mirosław (4):
  gpio: add gpiod_toggle_active_low()
  mmc: rework wp-gpio handling
  mmc: rework cd-gpio handling
  mmc: remove mmc_gpiod_request_*(invert_gpio)
