+Subject: [PATCH] brcmfmac: only support the BCM43455/7 device
+
+Recently support was added for the BCM4345 SDIO chipset by
+commit 9c51026509d7 ("brcmfmac: Add support for BCM4345 SDIO chipset")
+however this was verified using a BCM43455 device, which is
+a more recent revision of the chip. This patch assure that
+older revisions are not probed as they would fail.
