local/net: bcm4358: fix panic when unregistering p2p interfacesubmit/tizen/20170316.045621accepted/tizen/wearable/20170316.101819accepted/tizen/unified/20170316.101853accepted/tizen/tv/20170316.101804accepted/tizen/mobile/20170316.101734accepted/tizen/ivi/20170316.101834accepted/tizen/common/20170316.161713accepted/tizen_wearableaccepted/tizen_tvaccepted/tizen_mobileaccepted/tizen_iviaccepted/tizen_common
When unregistering p2p interface, following kernel panic occurs:
BUG: failure at mm/slub.c:3413/kfree()!
Kernel panic - not syncing: BUG!
CPU: 1 PID: 2698 Comm: wpa_supplicant Not tainted 4.1.36-arm64-tm2 #1

[<ffffffc0009e2204>] nl80211_set_wowlan+0x748/0x81c
...
It is because kfree(wdev->wiphy->wowlan_config) is called from
cfg80211_rdev_free_wowlan(), but it is assigned with const struct
pointer from the commit c1cdee9f047f ("LOCAL / net: bcm4358: set
wowlan_config for broadcom driver"). So this patch fixes to assign
it with kmemdup.
