Subject: mtd: maps: physmap: Fix coding style issues reported by checkpatch
X-Git-Tag: for-4.21~65^2~26
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=cb946bf6aaeb7c8151b18924d81370ffe6b7441b;p=uclinux-h8%2Flinux.git

mtd: maps: physmap: Fix coding style issues reported by checkpatch

Fix the following coding style issues:
- != NULL and == NULL test replaced by ! (or nothing)
- split over 80 chars lines
- add missing braces in multi-line if() {} else {} statements
