drivers/watchdog/lantiq_wdt.c: drop iounmap for devm_ allocated data Data allocated with devm_ioremap or devm_ioremap_nocache should not be freed using iounmap, because doing so causes a dangling pointer, and a subsequent double free. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r@ expression x; @@ ( x = devm_ioremap(...) | x = devm_ioremap_nocache(...) ) @@ expression r.x; @@ * iounmap(x) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
