stable inclusion from stable-v5.15 commit 0686082d category: feature bugzilla: https://gitee.com/openeuler/kernel/issues/I5WXCZ CVE: NA Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=0686082dbf7a204ca0fab326a820779e31666639 ---------------------------------------------------------------------- This adds a new callback to support device specific reset behavior. The vdpa bus driver will call the reset function instead of setting status to zero during resetting.

If `driver_override` is not set, the previous behaviour is followed: devices use the first vDPA bus driver loaded (unless auto binding is disabled). Tested on Fedora 34 with driverctl(8): $ modprobe virtio-vdpa $ modprobe vhost-vdpa $ modprobe vdpa-sim-net $ vdpa dev add mgmtdev vdpasim_net name dev1 # dev1 is attached to the first vDPA bus driver loaded $ driverctl -b vdpa list-devices dev1 virtio_vdpa $ driverctl -b vdpa set-override dev1 vhost_vdpa $ driverctl -b vdpa list-devices dev1 vhost_vdpa [*] Note: driverctl(8) integrates with udev so the binding is preserved.
