Subject: iio: hi8435: Use gpiod_set_value_cansleep()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6822dc9daa26102161e58a96b2ca938d14696006;p=linux.git

iio: hi8435: Use gpiod_set_value_cansleep()

Use gpiod_set_value_cansleep() instead of gpiod_set_value() to support
the case when reset pin is connected to a GPIO expander. See ZII VF610
SCU4 AIB for one such example.
