Subject: [PATCH v4 2/7] drm/nouveau/core: make use of new strlcpytolower() function

Call strlcpytolower() rather than copying the string explicitly and
then walking it to convert it to lowercase.

Signed-off-by: Markus Mayer <mmayer@...adcom.com>
---

The semantics of the new function has changed, so this patch has been
updated since v2 to match the new strlcpy() semantics (no explicit NULL
terminating is required).

See https://patchwork.kernel.org/patch/9215207/ for the previous version.
