drivers/macintosh/via-pmu.c: Added a missing iounmap
The error handling code should undo the ioremap as well. The problem was detected using the following semantic match (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ type T,T1,T2; identifier E; statement S; expression x1,x2; constant C; int ret; @@ T E; ... * E = ioremap(...); if (E == NULL) S ... when != iounmap(E) when != if (E != NULL) { ... iounmap(E); ...} when != x1 = (T1)E if (...) { ... when != iounmap(E) when != if (E != NULL) { ... iounmap(E); ...} when != x2 = (T2)E ( * return; | * return C; | * return ret; ) } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Johannes Berg <johannes@sipsolutions.net> Cc: Olaf Hering <olaf@aepfle.de> Cc: Benjamin Herrenschmidt <benh@kernel.crashing.org> Cc: Paul Mackerras <paulus@samba.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
