From 49367d8f1d9f26482cf7089489e90f0afd0a942c Mon Sep 17 00:00:00 2001 From: Ming Lei Date: Fri, 12 Dec 2008 21:38:45 +0800 Subject: USB: mark "reject" field of struct urb as atomic_t It is enough to protect accesses to reject field of urb by marking it as atomic_t,also it is the only reason of existence of usb_reject_lock,so remove the lock to make code more clean.
