Subject: mtd: spi-nor: Fix multiple coding style issues
X-Git-Url: http://git.dujemihanovic.xyz/%22http:/www.sics.se/static/git-logo.png?a=commitdiff_plain;h=a21cfc4e7c5380fb674989d2a00a9b9b7c42dd8e;p=u-boot.git

mtd: spi-nor: Fix multiple coding style issues

The offset variable is set, but never used afterward.
Fix indent. Fix predecrement without justification.
Remove use of parenthesis where unnecessary.

Fixes: 5d40b3d384dc ("mtd: spi-nor: Add parallel and stacked memories support")
