On some platforms the number of bits in the cbm_mask might not be divisible by 4 (and not even by 2), so we need to properly count the bits. Similar file, min_cbm_bits, is properly parsed and used, but if the number is greater than one, we lose the information about granularity when reporting the data in capabilities. For that matter always report granularity, but if it is not the same as the minimum, add that information in there as well. Signed-off-by: Martin Kletzander <mkletzan@redhat.com>
