Subject: [PATCH v3 3/9] ACPI: clean up checkpatch warnings for various bits of syntax
From: Al Stone <al.stone@...aro.org>
In preparation for later splitting out some of the arch-dependent code from
osl.c, clean up a bunch of warnings for odd bits of syntax:
-- remove CVS keyword markers
-- remove a space from between a function name and an opening parenthesis
-- clean up all but one line > 80 characters (one just looks silly if you
make it less than 80)
-- add blank lines after declarations in functions
-- remove extraneous braces ({})
Signed-off-by: Al Stone <al.stone@...aro.org>
