[PATCH] staging: bcm2835-audio: bcm2835.h: fix various coding style issues

From: Nathan Howard
Date: Fri Feb 17 2017 - 13:40:10 EST


The following coding style issues (as per checkpatch.pl) were resolved.

WARNING: Block comments use * on subsequent lines
WARNING: Prefer [subsystem eg: netdev]_info([subsystem]dev, ...
WARNING: Missing a blank line after declarations
WARNING: Use of volatile is usually wrong:...
WARNING: line over 80 characters
CHECK: Concatenated strings should use spaces between elements
CHECK: Macro argument 'vol' may be better as '(vol)' to avoid precedence issues
