[Intel-xe] [PATCH] drm/xe/uapi: Separate VM_BIND's operation and flag
Francois Dugast

Thu Sep 7 07:39:53 UTC 2023
Use different members in the drm_xe_vm_bind_op for op and for flags as
it is done in other structures.
Type is left to u32 to leave enough room for future operations and flags.
v2: Remove the XE_VM_BIND_* flags shift (Rodrigo Vivi)
