Hi Randy,

	thank you for the feedback.

I noticed that for some architectures (e.g., cris) these ioctls are defined also in arch/cris/include/asm/ioctls.h, and with different values with respect to the values defined on asm-generic/ioctls.h.

Therefore, I wasn't completely sure that the values defined in asm-generic are being used in every driver...

Oh, OK, I see.  Thanks for the info.
