[PATCH 1/1] initramfs: strcpy destination string overflow

[Evgeny Kuznetsov]

From: Evgeny Kuznetsov <ext-eugeny.kuznetsov@xxxxxxxxx>

Function "strcpy()" is used without check for maximum allowed
source string length and could cause destination string overflow.
"strcpy()" is replaced by "strlcpy()" to prevent destination
string overflow.
