parentarch/hexagon: fix kernel/dma.c build warning (diff)
hexagon: modify ffs() and fls() to return int
Building drivers/mtd/nand/raw/nandsim.c on arch/hexagon/ produces a printk format build warning. This is due to hexagon's ffs() being coded as returning long instead of int. Fix the printk format warning by changing all of hexagon's ffs() and fls() functions to return int instead of long. The variables that they return are already int instead of long. This return type matches the return type in <asm-generic/bitops/>. ../drivers/mtd/nand/raw/nandsim.c: In function 'init_nandsim': ../drivers/mtd/nand/raw/nandsim.c:760:2: warning: format '%u' expects argument of type 'unsigned int', but argument 2 has type 'long int' [-Wformat] There are no ffs() or fls() allmodconfig build errors after making this change.
