From ac019360fe311dd6aa11b358a02eb3a61675882e Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Sat, 20 Oct 2007 13:45:57 +0200 Subject: [Bluetooth] Eliminate checks for impossible conditions in IRQ handler Our info structure and info->hdev is always passed to the IRQ handler, so we don't have to worry about these checks in every interrupt. Leave a BUG_ON() just to help unwary programmers, but these could probably be removed as well.
