In the function brcms_c_regd_init() the channels are validated against the device capabilities. This is done for both 2.4G and 5G band, but there are devices that are 2.4G only, ie. BCM4313. For that device this leads to a NULL dereference. This patch adds a check in brcms_c_regd_init() to fix this. Issue introduced in wireless-next tree by following commit: cf03c5d brcm80211: smac: inform mac80211 of the X2 regulatory domain Cc: Seth Forshee <seth.forshee@xxxxxxxxxxxxx> Signed-off-by: Arend van Spriel <arend@xxxxxxxxxxxx> --- Noticed that one of smoketest machines actually was not sending results ever since I staged regulatory fixes for it. This particular system has a 2.4G card fitted so the root cause was quickly found. Gr.
