[PATCH 1/2] spi: rockchip: Convert to late and early system PM callbacks

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Currently we are suspending the spi master in it's ->suspend callback,
which is racy as some other drivers may still want to transmit messages
on the bus(e.g. spi based pwm backlight).

Convert to late and early system PM callbacks to avoid the race.
