Subject: net: stmmac: dwmac-sun8i: use return val of readl_poll_timeout()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=9e0db41e7a0b6f1271cbcfb16dbf5b8641b4e440;p=linux.git

net: stmmac: dwmac-sun8i: use return val of readl_poll_timeout()

When readl_poll_timeout() timeout, we'd better directly use its return
value.

Before this patch:
[    2.145528] dwmac-sun8i: probe of 4500000.ethernet failed with error -14

After this patch:
[    2.138520] dwmac-sun8i: probe of 4500000.ethernet failed with error -110
