This one didn't compile on an AM43xx-only build:

----
arch/arm/mach-omap2/built-in.o:(.data+0x3f2c): undefined reference to `omap2_dss_hwmod_class'
arch/arm/mach-omap2/built-in.o:(.data+0x405c): undefined reference to `omap2_rfbi_hwmod_class'
make: *** [vmlinux] Error 1
test_build: Tue Jul 22 13:48:50 MDT 2014: FAILED on omap2plus_defconfig_am43xx_only hwmod-a-v3.17
----

Have queued the following patch instead.
