[PATCH] Documentation: checkpatch: Tweak BIT() macro include

[Andrew Jeffery]

While include/linux/bitops.h brings in the BIT() macro, it was moved to
include/linux/bits.h in [1]. Since [1] BIT() has moved again into
include/vdso/bits.h via [2].

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

[1] commit 8bd9cb51daac ("locking/atomics, asm-generic: Move some macros from <linux/bitops.h> to a new <linux/bits.h> file")
[2] commit 3945ff37d2f4 ("linux/bits.h: Extract common header for vDSO")
