Subject[PATCH] hfsplus: Replace strncpy with memcpy
Date
Function strncpy was used to copy a fixed size buffer. Since
NUL-terminating string is not required here, prefer a memcpy function.
The generated code (ppc32) remains the same.

Silence the following warning triggered using W=1:

fs/hfsplus/xattr.c:410:3: warning: 'strncpy' output truncated before terminating nul copying 4 bytes from a string of the same length [-Wstringop-truncation]
