From 9600dcf1347d304cf4dff34ef50569d6584b6968 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Tue, 6 Jan 2009 17:20:58 +0100 Subject: [PATCH] ide: make "paranoia" ->handler check in ide_intr() more strict If ->handler is set while it shouldn't be it indicates deep problems so BUG_ON()-ning and preventing further damage is much more appropriate than merely printing an error message.
