Subject: [PATCH] net: dsa: microchip: Use gpiod_set_value_cansleep()
Date: Sun, 23 Jun 2019 14:10:36 +0200	[thread overview]
Message-ID: <20190623121036.3430-1-marex@denx.de> (raw)

Replace gpiod_set_value() with gpiod_set_value_cansleep(), as the switch
reset GPIO can be connected to e.g. I2C GPIO expander and it is perfectly
fine for the kernel to sleep for a bit in ksz_switch_register().
