Date: Sat, 25 Feb 2012 18:10:21 -0600 From: Larry Finger <Larry.Finger@...inger.net> To: gregkh@...uxfoundation.org Cc: Larry Finger <Larry.Finger@...inger.net>, linux-kernel@...r.kernel.org, devel@...verdev.osuosl.org Subject: [PATCH 2/2 V2] staging: r8712u: Fix regression caused by commit 8c213fa In commit 8c213fa "staging: r8712u: Use asynchronous firmware loading", the command to release the firmware was placed in the wrong routine. In combination with the bug introduced in commit a5ee652 "staging: r8712u: Interface-state not fully tracked", the driver attempts to upload firmware that had already been released. This bug is the source of one of the problems in https://bugs.archlinux.org/task/27996#comment89833.
