This patch-set attempts to fix checkpatch.pl issues found in nl80211.c.
Each patch describes the specific warnings/checks/errors it addresses.
This patch-set ignores 'line over 80 chars' warnings.
Please check for issues with the 'fixes' for 'alignment should match
open parenthesis'. Some of them do not display correctly with git diff.
This patch-set removes 3 errors, 66 warnings and 46 checks.

From: Kirtika Ruchandani @ 2016-05-29 3:31 UTC (permalink / raw)
To: Johannes Berg; +Cc: linux-wireless, ruchandani.tina, netdev
This patch fixes the following checkpatch.pl issues -
- space preferred around that <operator>
- no space needed after cast.
- braces {} should be used on all arms of this statement
- Alignment should match open parenthesis
- suspect code indent for conditional statements
- Statements should start on a tabstop
- multiple assignments should be avoided
- prefer ether_addr_copy over memcpy
- correct spelling - 'implementation'
- comparison to NULL could be written as !foo
- prefer kcalloc over kzalloc with multiply

Thanks, I will send out a v2 with the split you suggested.

Re-send the entire set, make sure you mark it as v2, include a
changelog in the cover letter or below the "---" in the patches
themselves, and don't forget to include the reviewed-bys for any
unchanged patches.
Thanks,

It's kinda mixed, I never really enforced one style or the other ...
I'm kinda taking both now, with a slight preference towards the
networking style perhaps (to please davem :) )
That said, in general I'm not really sure of the value of all of these
patches - perhaps the kcalloc() one makes sense, not for checkpatch
reasons but rather for size limit/integer overflow reasons, and the
ether address assign for general readability, but overall ...
I'll have to make up my mind :)
