Re: [PATCH 5/5] staging: sm750fb: deduplicate fbinfo loop in suspend/resume

[Dan Carpenter <error27@gmail.com>]

I was waiting to see if anyone had other comments bout this patchset
to decide if I should mention these minor nits.  But then I was
confused about v2 so I think there might end up being comments... :P

You didn't introduce this, but the rule is the multi-line indents get
curly braces for readabilitly even if they're not required.
