It matches the changes in the other series that I sent.

Before this change, the check of "brcm,bcm4329-fmac" compatible is set 
at the end of probe function for SDIO devices which need IRQ. But after 
this change I set it to the top as the first check. So I add this 
fallback compatible to the Apple's DTS.

Oh..I got what you mean. Maybe my commit message is not clearly. It is 
no need to mention driver in it. Because the intent of adding the 
"brcm,bcm4329-fmac" compatible is to conform to the bindings.
