Subject: [PATCH] staging: wlan-ng: fix exit return when sme->key_idx >=
NUM_WEPKEYS
commit 153c5d8191c26165dbbd2646448ca7207f7796d0 upstream.
Currently the exit return path when sme->key_idx >= NUM_WEPKEYS is via
label 'exit' and this checks if result is non-zero, however result has
not been initialized and contains garbage. Fix this by replacing the
goto with a return with the error code.
Addresses-Coverity: ("Uninitialized scalar variable")
Fixes: 0ca6d8e74489 ("Staging: wlan-ng: replace switch-case statements with macro")
