strcpy() performs no bounds checking on the destination buffer. This could result in linear overflows beyond the end of the buffer, leading to all kinds of misbehaviors. So, use memcpy() as a safe replacement. This is a previous step in the path to remove the strcpy() function entirely from the kernel. Signed-off-by: Len Baker <redacted>

i.e. will queue in renesas-devel for v5.15.
