[PATCH] ipc: whitespace cleanup
From: Manfred Spraul
Date: Mon Dec 23 2013 - 05:03:39 EST
The ipc code does not adhere the typical linux coding style.
This patch fixes all simple whitespace errors.
- mostly autogenerated by
scripts/checkpatch.pl -f --fix \
--types=pointer_location,spacing,space_before_tab
- one manual fixup (keep structure members tab-aligned)
diff -w is empty.
Tested with some msg and sem test apps.
