I suppose Gustavo meant that there are maintainers in the community
(and I am part of it) that do not like when people fix style issues
aside their own changes -specifically without writing it in commit
logs. But in this situation I think s/printk(KEN_NOTICE/pr_notice(/
needs the second line to be re-aligned with the first one. While
touching it, it seems reasonable to also fix this style issue and avoid
keeping broken strings.

Thanks,
Miquèl
