bitops: remove duplicated extern declarations
If CONFIG_GENERIC_FIND_NEXT_BIT is enabled, find_next_bit() and find_next_zero_bit() are doubly declared in asm-generic/bitops/find.h and linux/bitops.h. asm/bitops.h includes asm-generic/bitops/find.h if and only if the architecture enables CONFIG_GENERIC_FIND_NEXT_BIT. And asm/bitops.h is included by linux/bitops.h So we can just remove the extern declarations of find_next_bit() and find_next_zero_bit() in linux/bitops.h. Also we can remove unneeded #ifndef CONFIG_GENERIC_FIND_NEXT_BIT in asm-generic/bitops/find.h. Signed-off-by: Akinobu Mita <akinobu.mita@gmail.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
