Subject: [PATCH] skge: fifo control register access fix
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d8a09943ebbaca9befd995d8fe10dd9885256dbf;p=openwrt%2Fstaging%2Fblogic.git

[PATCH] skge: fifo control register access fix

The code to clear fifo errors was incorrect and sending garbage
to the external phy. Removed the no longer used inline's funcs.
