This time after the merging usb trees:

drivers/phy/qualcomm/phy-qcom-usb-hs.o: warning: objtool: file already has .orc_unwind section, skipping
make[3]: *** [scripts/Makefile.modfinal:61: drivers/phy/qualcomm/phy-qcom-usb-hs.ko] Error 255
drivers/phy/qualcomm/phy-qcom-usb-hsic.o: warning: objtool: file already has .orc_unwind section, skipping
make[3]: *** [scripts/Makefile.modfinal:61: drivers/phy/qualcomm/phy-qcom-usb-hsic.ko] Error 255

I just removed the drivers/phy/qualcomm directory from the object tree
and rebuilt.

Then got this:

drivers/phy/ti/phy-tusb1210.o: warning: objtool: file already has .orc_unwind section, skipping
make[3]: *** [/home/sfr/next/next/scripts/Makefile.modfinal:61: drivers/phy/ti/phy-tusb1210.ko] Error 255

So removed the drivers/phy/ti directory and rebuilt and the build
succeeded.

I assume that something is being left around or reprocessed when it
should not be.
