+Subject: [PATCH] brcmfmac: Avoid possible out-of-bounds read
+
+In brcmf_p2p_notify_rx_mgmt_p2p_probereq(), chanspec is assigned before
+the length of rxframe is validated. This could lead to uninitialized
+data being accessed (but not printed). Since we already have a
+perfectly good endian-swapped copy of rxframe->chanspec in ch.chspec,
+and ch.chspec is not modified by decchspec(), avoid the extra
+assignment and use ch.chspec in the debug print.

+Subject: [PATCH] brcmfmac: handle FWHALT mailbox indication
+
+The firmware uses a mailbox to communicate to the host what is going
+on. In the driver we validate the bit received. Various people seen
+the following message:
+
+ brcmfmac: brcmf_sdio_hostmail: Unknown mailbox data content: 0x40012
+
+Bit 4 is cause of this message, but this actually indicates the firmware
+has halted. Handle this bit by giving a more meaningful error message.
