staging: rtl8188eu: Fix incorrect response to SIOCGIWESSID
[ Upstream commit b77992d2df
]
When not associated with an AP, wifi device drivers should respond to the
SIOCGIWESSID ioctl with a zero-length string for the SSID, which is the
behavior expected by dhcpcd.
Currently, this driver returns an error code (-1) from the ioctl call,
which causes dhcpcd to assume that the device is not a wireless interface
and therefore it fails to work correctly with it thereafter.
This problem was reported and tested at
https://github.com/lwfinger/rtl8188eu/issues/234.
