[PATCH] fix infoleak in wireless

From: Kangjie Lu
Date: Tue May 03 2016 - 16:37:21 EST


The 6-bytes array âmac_addrâ is not initialized in the dump_station
implementations of âdrivers/staging/wilc1000/wilc_wfi_cfgoperations.câ
and âdrivers/staging/rtl8723au/os_dep/ioctl_cfg80211.câ, so all 6
bytes may be leaked.
