From 1548b13b75a2ec06f46220004e91c37818be6c18 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 1 Jun 2010 23:04:44 +0200 Subject: [PATCH] usb: gadget: Do not take BKL for gadget->ops->ioctl MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit There is no gadget driver in the tree that actually implements the ioctl operation, so obviously it is not necessary to hold the BKL around the call.
