[PATCH 154/342] Staging: wlan-ng: p80211wext.c: problem with IW_ENCODE_ALG_WEP

[gregkh at suse.de (Greg Kroah-Hartman)]

From: Julia Lawall <julia at diku.dk>

The expression !(ext->alg & IW_ENCODE_ALG_WEP) appears to be incorrect,
because there are several possible values for ext->alg that give 1 when
bit-anded with IW_ENCODE_ALG_WEP.  Therefore Richard Kennedy suggested to
rewrite the code with !=

Added \n at the end of the debug string as well.
