[PATCH] Removing deprecated strncpy()

[Kevin Paul Reddy Janagari <kevinpaul468@gmail.com>]

This patch suggests the replacement of strncpy with strscpy
as per the Documentation/process/deprecated
the strncpy() fails to guarntee NULL termination
since the function adds zero pads, this isn't really convenient
for short strings as it may cause performce issues

strscpy() is a preffered replacement because
it overcomes the limitations of strncpy as mentioned above
