Revision 3b25528e1e355c803e73aa326ce657b5606cda73 authored by Chen-Yu Tsai on 29 August 2019, 03:17:24 UTC, committed by David S. Miller on 30 August 2019, 21:16:26 UTC
The devicetree binding lists the phy phy as optional. As such, the driver should not bail out if it can't find a regulator. Instead it should just skip the remaining regulator related code and continue on normally. Skip the remainder of phy_power_on() if a regulator supply isn't available. This also gets rid of the bogus return code. Fixes: 2e12f536635f ("net: stmmac: dwmac-rk: Use standard devicetree property for phy regulator") Signed-off-by: Chen-Yu Tsai <wens@csie.org> Signed-off-by: David S. Miller <davem@davemloft.net>
