Subject: drm/vmwgfx: Report vmwgfx version to vmware.log
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f921791314811afa00bb7fbbd40f51bd3b8eff01;p=linux.git

drm/vmwgfx: Report vmwgfx version to vmware.log

When tracking down a customer issue, it is useful to know exactly
which version of the vmwgfx they are using.  Since vmware.log is
often the only available debug log, report vmwgfx version in there.
