Subject: staging: r8712u: Fix regression caused by commit 8c213fa
From: Larry Finger <[email protected]>
commit 2080913e017ab9f88379d93fd09546ad95faf87b upstream.
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.
