Subject: wl1271: set null data template when BSSID is known
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=bdcbbb947be9778f740797a2bfc69c44a0d54776;p=deliverable%2Flinux.git

wl1271: set null data template when BSSID is known

The call to wl1271_cmd_build_null_data() was missing when we got associated,
this was causing PS to fail.  This patch adds the call and now PS seems to
work.
