[PATCH 2/2] drivers: staging: media: atomisp: fix coding style warnings

From: Avraham Shukron
Date: Sun May 07 2017 - 17:58:55 EST


Fix for warnings reported by checkpatch.pl:
- Multiline comment style
- Bare "unsigned"
- Missing blank line after declarations
- Un-needed braces around single-statement branch
