X-Git-Tag: v2020.07-rc2~18^2~38
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=5a0c332a8a6fee7deadda5c8439782aa5f7b9ca2;p=oweals%2Fu-boot.git

net: dc2114x: Clean up send_setup_frame()

Clean up the send_setup_frame() to bring it up to standards with
U-Boot coding style, invert the loops where applicable to cut
down the level of indent. No functional change.
