Subject: net: enetc: remove forward-declarations of enetc_clean_{rx,tx}_ring
X-Git-Tag: v5.15~1236^2~591^2~2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=8580b3c3d786e739e6073438d1da0218ca436939;p=platform%2Fkernel%2Flinux-starfive.git

net: enetc: remove forward-declarations of enetc_clean_{rx,tx}_ring

This patch moves the NAPI enetc_poll after enetc_clean_rx_ring such that
we can delete the forward declarations.
