commit 87279fdf5ee0ad1360765ef70389d1c4d0f81bb6 upstream.
Fix the following errors & warnings reported by checkpatch:
ERROR: space required before the open brace '{' ERROR: space required before the open parenthesis '(' ERROR: that open brace { should be on the previous line ERROR: space prohibited before that ',' (ctx:WxW) ERROR: else should follow close brace '}' ERROR: open brace '{' following function definitions go on the next line ERROR: code indent should use tabs where possible
WARNING: braces {} are not necessary for single statement blocks WARNING: void function return statements are not generally useful WARNING: Block comments use * on subsequent lines WARNING: Block comments use a trailing */ on a separate line
