[PATCH v2 0/2] gpio: drop bitmap_complement() where feasible

The gpio drivers reproduce the following pattern:

	bitmap_complement(tmp, data1, nbits);
	bitmap_and(dst, data2, tmp, nbits);

This can be done in a single pass:

	bitmap_andnot(dst, data2, data1, nbits);

v1: https://lore.kernel.org/all/20260417033439.318930-1-ynorov@nvidia.com/
v2: 
 - cleanup typos (Michal);
 - split per individual drivers (Andy).
