[ Upstream commit 50935044e58e563cdcfd556d62f27bc8744dd64e ]
Use gpiod_set_value_cansleep() instead of gpiod_set_value() to fix the below call trace in the boot log:
[ 5.690534] Call trace: [ 5.690536] gpiod_set_value+0x40/0xa4 [ 5.690540] anx7625_runtime_pm_resume+0xa0/0x324 [anx7625] [ 5.690545] __rpm_callback+0x48/0x1d8 [ 5.690549] rpm_callback+0x6c/0x78
Certain GPIO controllers require access via message-based buses such as I2C or SPI, which may cause the GPIOs to enter a sleep state. Therefore, use the gpiod_set_value_cansleep().
