From bcad6e80f3fb0d6724c3814cf32258bbcf1d67db Mon Sep 17 00:00:00 2001 From: David Kilroy Date: Sat, 1 May 2010 14:05:40 +0100 Subject: orinoco: encapsulate driver locking Local bus and USB drivers will need to do locking differently. The original orinoco_usb patches had a boolean variable controlling whether spin_lock_bh was used, or irq based locking. This version provides wrappers for the lock functions and the drivers specify the functions pointers needed. This will introduce a performance penalty, but I'm not expecting it to be noticable.
