Peter Huewe 67a88e6390 staging/rtl8192u/ieee80211: Fix buffer overflow in ieee80211_softmac_wx.c
Clang/scan-build complains about a possible buffer overflow in
ieee80211_wx_get_name:

.../staging/rtl8192u/ieee80211/ieee80211_softmac_wx.c:499:3:
warning: String copy function overflows destination buffer
	strcat(wrqu->name," link..");

.../staging/rtl8192u/ieee80211/ieee80211_softmac_wx.c:497:3:
warning: String copy function overflows destination buffer
	strcat(wrqu->name," linked");

The buffer wrqu->name is only IFNAMSIZ bytes big (currently 16),
so if we have a "802.11b/g/n linked" device we overrun the buffer by 3
bytes.

-> Use strlcopy / strlcat to populate the name.
This is done in a similar fashion in
staging/rtl8187se/ieee80211/ieee80211_softmac_wx.c

While at it cleaned some whitespace issues.

David Chosrova 0e7a3e7a74 Staging: rtl8192u: remove dead code to disable dot11d
This patch removes all the ENABLE_DOT11D ifdefs.
It is always defined for driver. DOT11D has to do with regulatory domains.

What prompted this patch was a warning message in Sparse.

drivers/staging/rtl8192u/r8192U_core.c:247:1: warning: "eqMacAddr"
redefined in file included from drivers/staging/rtl8192u/:81:81:
drivers/staging/rtl8192u/dot11d.h:35:1: warning: this is the location
of the previous definition

Now there are no ifdefs around dot11d.h it made no sense to have this
second definition, so I removed that macro as well. ( Thanks Dan ;-) ).
