SELinux: whitespace and formating fixes for hooks.c
All whitespace and formatting. Nothing interesting to see here. About the only thing to remember is that we aren't supposed to initialize static variables to 0/NULL. It is done for us and doing it ourselves puts them in a different section. With this patch running checkpatch.pl against hooks.c only gives us complaints about busting the 80 character limit and declaring extern's in .c files. Apparently they don't like it, but I don't feel like going to the trouble of moving those to .h files... Signed-off-by: Eric Paris <eparis@redhat.com> Signed-off-by: James Morris <jmorris@namei.org>
