This patchset originally start out as a replacement for
bitmap_get_value8/bitmap_set_value8/for_each_set_clump8, which are used
outside of the GPIO subsystem. Over the course of the revisions, the
scope of this patchset was reduced down and now it's only affecting GPIO
drivers.

You're right that this shouldn't be going into lib anymore because it's
gpiolib-only now. I expect the next revision of this patchset Syed
submits will address that.
