[PATCH 5/6] devfreq: rk3399_dmc: do not print error when get supply and clk defer.

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

 



From: Lin Huang <hl@xxxxxxxxxxxxxx>

We just return -EPROBE_DEFER error code to caller and do not
print error message when try to get center logic regulator
and DMC clock defer.
