__u64 drm_pvr_dev_query_quirks::quirks

@quirks: A userspace address for the hardware quirks __u32 array.

The first @musthave_count items in the list are quirks that the client must support for this device. If userspace does not support all these quirks then functionality is not guaranteed and client initialisation must fail. The remaining quirks in the list affect userspace and the kernel or firmware. They are disabled by default and require userspace to opt-in. The opt-in mechanism depends on the quirk.
