sh: use generic strncpy()

2020-08-15T02:56:57+00:00

Current SH will get below warning at strncpy() In file included from ${LINUX}/arch/sh/include/asm/string.h:3, from ${LINUX}/include/linux/string.h:20, from ${LINUX}/include/linux/bitmap.h:9, from ${LINUX}/include/linux/nodemask.h:95, from ${LINUX}/include/linux/mmzone.h:17, from ${LINUX}/include/linux/gfp.h:6, from ${LINUX}/innclude/linux/slab.h:15, from ${LINUX}/linux/drivers/mmc/host/vub300.c:38: ${LINUX}/drivers/mmc/host/vub300.c: In function 'new_system_port_status': ${LINUX}/arch/sh/include/asm/string_32.h:51:42: warning: array subscript\ 80 is above array bounds of 'char[26]' [-Warray-bounds] : "0" (__dest), "1" (__src), "r" (__src+__n) ~~~~~^~~~ In general, strncpy() should behave like below. char dest[10]; char *src = "12345"; strncpy(dest, src, 10); // dest = {'1', '2', '3', '4', '5', '\0','\0','\0','\0','\0'} But, current SH strnpy() has 2 issues. 1st is it will access to out-of-memory (= src + 10). 2nd is it needs big fixup for it, and maintenance __asm__ code is difficult. To solve these issues, this patch simply uses generic strncpy() instead of architecture specific one.

sh: remove KERNEL ifdefs from non-UAPI headers
