Obviously, the commit message would have to be rewritten
for a real patch.

This code (vendor upstream?) is probably relevant:
https://github.com/StreamUnlimited/broadcom-bcmdhd-4359/blob/master/include/bcmdevs.h

#define BCM4362_CHIP_ID		0x4362          /* 4362 chipcommon chipid */
#define BCM43751_CHIP_ID	0xAAE7          /* 43751 chipcommon chipid */
#define BCM43752_CHIP_ID	0xAAE8          /* 43752 chipcommon chipid */


#define BCM4362_CHIP(chipid)	((CHIPID(chipid) == BCM4362_CHIP_ID) || \
				(CHIPID(chipid) == BCM43751_CHIP_ID) || \
				(CHIPID(chipid) == BCM43752_CHIP_ID))

#define BCM4362_CHIP_GRPID	BCM4362_CHIP_ID: \
				case BCM43751_CHIP_ID: \
				case BCM43752_CHIP_ID
