Are you looking for ffs() from <linus/bitops.h>?

find-first-set (the include boils down to include/asm-generic/bitops/ffs.h
if you want to check the implementation).

Thanks, but it might not solve the issue. :(
Actually this will retain the first Least Significant Bit (which is 1)
and will mark all other zero. So it will give output 0b10 for 0b110

Oops!! I didn't looked at fls in the implementation. :(
You are right. This will solve my issue.
