commit 5c3de777bdaf48bd0cfb43097c0d0fb85056cab7 upstream. In the function brcmf_sdio_firmware_callback() the driver is unbound from the sdio function devices in the error path. However, the order in which it is done resulted in a use-after-free issue (see brcmf_ops_sdio_remove() in bcmsdh.c). Hence change the order and first unbind sdio function #2 device and then unbind sdio function #1 device.
