Unsupported WiFi adapter on S905X2 board

[Marc Gonzalez <marc.w.gonzalez@xxxxxxx>]

Hello,

I think there's an unsupported device in this system:

# cat /sys/bus/sdio/devices/mmc2:0001:1/uevent
OF_NAME=wifi
OF_FULLNAME=/soc/sd@ffe03000/wifi@1
OF_COMPATIBLE_0=brcm,bcm4329-fmac
OF_COMPATIBLE_N=1
SDIO_CLASS=00
SDIO_ID=02D0:AAE7
SDIO_REVISION=0.0
MODALIAS=sdio:c00v02D0dAAE7

0xaae7 = 43751

Isn't there some overlap between
include/linux/mmc/sdio_ids.h
and
drivers/net/wireless/broadcom/brcm80211/include/brcm_hw_ids.h
?

(Relevant commit: d2587c57ffd8dc)

Looking at all the occurrences of 43752 to insert a 43751,
could someone comment whether this looks reasonable?
