From: Arnd Bergmann <arnd@arndb.de>

Since commit d26270061ae6 ("string: Remove strlcpy()"), the strlcpy()
function causes a build failure.

Since the return value is ignored, changing it to the strscpy()
causes no change in behavior but fixes the build failure.

Fixes: f237c83e4302 ("drm: apple: DCP AFK/EPIC support")
