Subject: CRIS: macro whitespace fixes in uaccess.h
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=83f1588e9f770832b3446324110ff5b71e5f017c;p=openwrt%2Fstaging%2Fblogic.git

CRIS: macro whitespace fixes in uaccess.h

While working on arch/cris/include/asm/uaccess.h, I noticed
that some macros within this header are made harder to read because they
violate a coding style rule: space is missing after comma.

Fix it up.
