This patch replaces all the existing for_each_set_clump8 and related
function calls in the drivers (gpio and thermal) with the equivalent
new generic for_each_set_clump macro.

Why are patches [3/6] and [4/6] included in v2 even though William
said they should be ignored?

Again, replacing for_each_set_clump8() with for_each_set_clump()
does not provide any benefit but may impact performance and makes
the code more difficult to follow.  So once more, please do not
change drivers which are known to work fine with 8 bit clumps,
specifically gpio-max3191x.c and gpio-74x164.c.

Please in the future include a list of the changes you've made
in the cover letter, not just in each individual patch.

Thanks,

Lukas

Hi Lukas,
Your concerns are noted. [3/6] and [4/6] won't be included in the next
version v3 of the patchset.
