[PATCH] pinctrl: stm32: fix compile error and modernize
From: Linus Walleij <hidden>
Date: 2016-02-05 22:49:35
- Fix the dev->parent assignment compile error - Use gpiochip_get_data() to get the data pointer for the banks Cc: Maxime Coquelin <mcoquelin.stm32@gmail.com> Cc: Patrice Chotard <redacted> Signed-off-by: Linus Walleij <redacted> --- I don't even know how to compile test this, I hope it works, Maxime can you verify? --- drivers/pinctrl/stm32/pinctrl-stm32.c | 15 ++++++--------- 1 file changed, 6 insertions(+), 9 deletions(-)
