Staging: at76_usb: fix bugs introduced by "Staging: at76_usb: cleanup dma on stack issues"
Tracking down the firmware loading problem led to this commit. $ git bisect bad 0d1d1424330cc1934f2b2742f0cfa2c31e6a250b is first bad commit commit 0d1d1424330cc1934f2b2742f0cfa2c31e6a250b Author: Oliver Neukum <oliver@neukum.org> Date: Thu Dec 18 13:16:40 2008 +0100 Staging: at76_usb: cleanup dma on stack issues - no DMA on stack - cleanup unclear endianness issue Signed-off-by: Oliver Neukum <oneukum@suse.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> :040000 040000 c4fee9ea0fef25926229d810d19dc2f89cca9401 8b165a35d16280d2413b2700a6080ef290ca1009 M drivers The "no DMA on stack" conversion was incomplete with respect to updating the arguments passed to usb_control_msg. The value 40 is hardcoded as it was prior to conversion. The driver can now load firmware, but is not fully functional. Signed-off-by: Jason Andryuk <jandryuk@gmail.com> Cc: John W.
