[PATCH 01/17] bitops: protect find_first_{,zero}_bit properly

[Yury Norov]

find_first_bit() and find_first_zero_bit() are not protected with
ifdefs as other functions in find.h. It causes build errors on some
platforms if CONFIG_GENERIC_FIND_FIRST_BIT is enabled.

Signed-off-by: Yury Norov <yury.norov@xxxxxxxxx>
Fixes: 2cc7b6a44ac2 ("lib: add fast path for find_first_*_bit() and find_last_bit()")
Reported-by: kernel test robot <lkp@xxxxxxxxx>
Tested-by: Wolfram Sang <wsa+renesas@xxxxxxxxxxxxxxxxxxxx>
