[PATCH 0/2] Convert to persistent DRM devices

[Jeffrey Hugo]

The qaic driver currently creates and destroys the DRM devices when the
qaic device is in an operational state for userspace. This does not match
what other DRM drivers do, and leads to a few race conditions that need
to be handled.

Instead, create the DRM device when the underlying PCIe device is detected
and destroy the DRM device when the underlying device disappears.

Use KOBJ_ONLINE/OFFLINE udev events to signal to userspace when the
underlying device is ready to accept requests, or has entered a reset
state.
