arc: [plat-eznps] fix printk warning in arc/plat-eznps/mtm.c
Fix printk format warning in arch/arc/plat-eznps/mtm.c: In file included from ../include/linux/printk.h:7, from ../include/linux/kernel.h:14, from ../include/linux/list.h:9, from ../include/linux/smp.h:12, from ../arch/arc/plat-eznps/mtm.c:17: ../arch/arc/plat-eznps/mtm.c: In function 'set_mtm_hs_ctr': ../include/linux/kern_levels.h:5:18: warning: format '%d' expects argument of type 'int', but argument 2 has type 'long int' [-Wformat=] #define KERN_SOH "\001" /* ASCII Start Of Header */ ^~~~~~ ../include/linux/kern_levels.h:11:18: note: in expansion of macro 'KERN_SOH' #define KERN_ERR KERN_SOH "3" /* error conditions */ ^~~~~~~~ ../include/linux/printk.h:308:9: note: in expansion of macro 'KERN_ERR' printk(KERN_ERR pr_fmt(fmt), ##__VA_ARGS__) ^~~~~~~~ ../arch/arc/plat-eznps/mtm.c:166:3: note: in expansion of macro 'pr_err' pr_err("** Invalid @nps_mtm_hs_ctr [%d] needs to be [%d:%d] (incl)\n", ^~~~~~ ../arch/arc/plat-eznps/mtm.c:166:40: note: format string is defined here pr_err("** Invalid @nps_mtm_hs_ctr [%d] needs to be [%d:%d] (incl)\n", ~^ %ld The hs_ctr variable can just be int instead of long, so also change kstrtol() to kstrtoint() and leave the format string as %d. Also add 2 header files since they are used in mtm.c and we prefer not to depend on accidental/indirect #includes.
