From 5c41aaad409c097cf1ef74f2c649fed994744ef5 Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Sun, 22 Jul 2018 16:03:58 -0700 Subject: [PATCH] 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 . ../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.
