From 41f2c6e89cf4d412e4b20803f5feb2b9b1560476 Mon Sep 17 00:00:00 2001 From: Alessio Igor Bogani Date: Mon, 1 Mar 2010 14:10:56 +0100 Subject: [PATCH] USB: sisusbvga: Remove the BKL from ioctl Seems to me that BKL is not needed here because necessary locking is already provided by mutex sisusb->lock. Also change the returned value to long.
