From: Corey Minyard Date: Tue, 29 Apr 2008 08:01:09 +0000 (-0700) Subject: ipmi: style fixes in the base code X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c70d749986f6f1d4e2bb008bfc0c5fc22ec3fc64;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ipmi: style fixes in the base code Lots of style fixes for the base IPMI driver. No functional changes. Basically fixes everything reported by checkpatch and fixes the comment style.
