While include/linux/bitops.h brings in the BIT() macro, it was moved to
include/linux/bits.h in commit 8bd9cb51 ("locking/atomics, asm-generic:
Move some macros from <linux/bitops.h> to a new <linux/bits.h> file").

Since that commit BIT() has moved again into include/vdso/bits.h via
commit 3945ff37 ("linux/bits.h: Extract common header for vDSO").

I think the move to the vDSO header can be considered an implementation
detail, so for now update the checkpatch documentation to recommend use
of include/linux/bits.h.

It should use post_handler instead of pre_handler in handler_post().

As Joe Perches suggested, it would be better to use pr_fmt and remove
all the embedded pre/post/fault strings. This would change the style of
the output through.

./scripts/get_abi.pl is warning about duplicated symbol
definition:

What happens is that 3 drivers use the same pattern to report
max and dim setting for different ambient light zones.

It should be noticed that the adp8870 doc was missing an
entry for l1_daylight_dim, which was fixed on this patch.

While the ambient light zone is device-specific, the sysfs
definition is actually common. So, unify them at:

	Documentation/ABI/testing/sysfs-class-backlight

While UTF-8 characters can be used at the Linux documentation,
the best is to use them only when ASCII doesn't offer a good replacement.
So, replace the occurences of the following UTF-8 characters:

In this specific case, EN DASH was used instead of a minus
