The register read function is referencing the dev->ctrlmsg structure outside of the dev->mutex lock, which can cause corruption of the value if multiple callers are invoking au0828_readreg() simultaneously. Use a stack variable to hold the result, and copy the buffer returned by usb_control_msg() to that variable. In reality, the whole recv_control_msg() function can probably be collapsed into au0288_readreg() since it is the only caller. Also get rid of cmd_msg_dump() since the only case in which the function is ever called only is ever passed a single byte for the response (and it is already logged).
