Subject: [PATCH v6 5/5] drm/nouveau/drm: Bump the driver version to 1.4.1
 to report new features

From: Mohamed Ahmed <mohamedahmedegypt2001@...il.com>

The HW can only do compression on large and huge pages, and enabling it on
4K pages leads to a MMU fault. Compression also needs kernel support for
handling the compressed kinds and managing the compression tags.

This increments the nouveau version number which allows NVK to enable it
only when the kernel actually supports both features and avoid breaking
the system if a newer mesa version is paired with an older kernel version.
