+Subject: [PATCH] brcmfmac: defer DPC processing during probe
+
+The sdio dpc starts processing when in SDIOD_STATE_DATA. This state was
+entered right after firmware download. This patch moves that transition
+just before enabling sdio interrupt handling thus avoiding watchdog
+expiry which would put the bus to sleep while probing.
