[PATCH] arch/h8300: modify ffs(), fls() etc. functions to return int

[Randy Dunlap]

From: Randy Dunlap <rdunlap@xxxxxxxxxxxxx>

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 ffx() and
flx() functions to return int instead of long.  The variables that
they return are already int instead of long.

../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 ffx() or flx() allmodconfig build errors after making this
change.
