From: Guenter Roeck Date: Sat, 4 Apr 2015 16:05:57 +0000 (-0700) Subject: hwmon: (it87) Formatting cleanup X-Git-Tag: v4.7-rc1~176^2~6 X-Git-Url: http://git.cascardo.info/?p=cascardo%2Flinux.git;a=commitdiff_plain;h=c962024e306ed598600853854a067b521bf5b530 hwmon: (it87) Formatting cleanup Fix various checkpatch complaints to clean up the code and make it easier to read. CHECK: Do not include the paragraph about writing to the FSF CHECK: Alignment should match open parenthesis CHECK: Logical continuations should be on the previous line CHECK: No space is necessary after a cast CHECK: Please don't use multiple blank lines CHECK: Please use a blank line after function/struct/union/enum declarations CHECK: spaces preferred around that '+' (ctx:VxV) WARNING: Missing a blank line after declarations No functional change.
