trivial: cleanup hpfall example code (checkpatch)
This patch makes hpfall.c conform to kernel coding style. I have not fixed the C99 // comments on two lines as they help indicate that those are not actually comments but incomplete code. Before: total: 10 errors, 6 warnings, 101 lines checked After: total: 2 errors, 0 warnings, 99 lines checked Signed-off-by: Frans Pop <elendil@planet.nl> Acked-by: Pavel Machek <pavel@ucw.cz> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
