Good point. The commit is c4670dfcbe52b598e263c452762a66d22e636585.

I just upgraded to 309f3805ddec9ab2f9c62da573586a7cf7c1f17a and still
observe that it uses a lot of memory.

I ran
make CC="gcc -save-temps -D__CHECKER__" KBUILD_NOCMDDEP=1 M=drivers/net/wireless/mac80211/rt2x00/
and aborted when I got lots of errors, rt2400pci.i was created and has
about 26k lines. Running sparse on it (sparse rt2400pci.i) takes a lot
of memory too. I put the file up at
http://johannes.sipsolutions.net/files/rt2400pci.i
