2017-04-28staging: rtl8723bs: declare private function as staticKenneth Hsu1-1/+2
This fixes a sparse warning regarding an undeclared symbol. Since the function is private to rtw_recv.c, it should be declared as static. Signed-off-by: Kenneth Hsu <kennethhsu@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2017-04-28staging: gdm724x: gdm_mux: fix use-after-free on module unloadJohan Hovold1-2/+1
Make sure to deregister the USB driver before releasing the tty driver to avoid use-after-free in the USB disconnect callback where the tty devices are deregistered.

2017-04-28staging: rtl8188eu: prevent an underflow in rtw_check_beacon_data()Dan Carpenter1-1/+1
The "len" could be as low as -14 so we should check for negatives. Fixes: 9a7fe54ddc3a ("staging: r8188eu: Add source files for new driver - part 1") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
