Subject: drm/xe/pf: Disable VFs on remove
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=8d789ff4a41a557de565b1778a7c620cbb22ae0e;p=users%2Fdwmw2%2Flinux.git

drm/xe/pf: Disable VFs on remove

We shouldn't leave VFs enabled when unloading the PF driver.
Otherwise we will get a message like:

 [ ] xe 0000:4d:00.0: driver left SR-IOV enabled after remove
