From: Alan Stern Date: Tue, 7 Jul 2009 13:50:14 +0000 (-0400) Subject: USB: Sierra: fix oops upon device close X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7bae0a070db4bc2761dd9515f450cdfa3f3f248c;p=openwrt%2Fstaging%2Fblogic.git USB: Sierra: fix oops upon device close This patch (as1263) fixes a mixup that occurred when conflicting patches for the sierra driver were merged incorrectly. The former sierra_shutdown routine should have been become sierra_release, not sierra_disconnect. The symptom this fixes is an oops when the device file is closed after a Sierra device has been unplugged (Bugzilla #13675).
