Hi All!

Actually there are much more unused header files:

Ok to drop, I think.

> ./arch/arm/include/asm/arch-check.h

This one is referenced from arch/arm/Makefile

> ./arch/powerpc/include/asm/status_led.h
> ./arch/x86/include/asm/modes.h

Ok to drop, I think.

This is included in drivers/mtd/nand/atmel/legacy.c.
(I see now you mentioned that below)

> ./drivers/usb/host/ehci-core.h

Ok to drop, I think.

> ./fs/fat/ffconf.h

This likewise looks as if it is actually used.
(I see now you mentioned that below)

> ./include/gpiod.h

This one here is an intentional compatibility header for out-of-tree
board code.

> ./include/linux/mtd/ndfc.h
> ./include/linux/mtd/nftl.h
> ./include/linux/usb/usbroothubdes.h

Ok to drop, I think.

> ./include/mach/imx/ccm.h

I think this should be dropped. I am unsure this even applies to all CCM
versions. It can always be brought back with a correct imxVER suffix.

These are non-DT device creation helpers. Maybe Sascha has an opinion
on whether they should be kept or removed?

> ./include/mach/imx/habv3-imx25-gencsf.h

There's i.MX25 support in drivers/hab, which I assume was added for a reason,
so some out-of-tree board is likely including this. 

> ./include/mach/imx/iomux-mx21.h
> ./include/mach/imx/iomux-mx35.h
> ./include/mach/imx/iomux-mx50.h

I think these definitions should remain. It's not unlikely that out-of-tree
boards use them.

I am ok with dropping the other headers if indeed unreferenced.

Maybe exclude #, so also #  include and gcc -include is matched.


Cheers,
Ahmad
