Subject: [PATCH v1 1/1] ata: Drop unneeded inclusion of kernel.h in the header

There is no need to have kernel.h included, I do not see any
direct users of it in ata.h. Drop unneeded inclusion of kernel.h.

Thanks, we need to include bits.h.
(It passed my simple build, but appears I have no such driver included)

Jens, I saw your message, should I send a follow up fix, or a v2?

Because kernel.h inclusion seems to me too wrong there.

that has been thought about and went through full compilation, then
you can resend it.
