[PATCH v2 1/3] ARC: bitops: Change __fls to return unsigned long

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



As per asm-generic definition and other architectures __fls should
return unsigned long.

No functional change is expected as return value should fit in unsigned
long.
