Hi,
FYI, your patch has been queued to stable release 20.11.10
Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/10/23. So please
shout if anyone has objections.
Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.
Queued patches are on a temporary branch at:
https://github.com/bluca/dpdk-stable
This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/e4af517678060237c39666b0cd50734b791c82a3
Thanks.

Subject: [PATCH] eventdev: fix device pointer for vdev-based devices
[ upstream commit 928b5c701f254c64a7adb0051c0cfd25e8365584 ]
The eventdevs based on vdevs, rather than on e.g. HW PCI devices, were,
as a rule, not setting the ".dev" pointer in the eventdev structure.
This caused issues as a NULL pointer was returned in calls to info_get,
triggering crashes if the pointer is passed unchecked to e.g.
rte_dev_name() to print out the name of an event device.
Most effective, and future-proofed fix, is to not rely on the eventdev
drivers to set the pointer themselves, but to change the vdev init
function to take the vdev struct as parameter, and set the "dev" pointer
centrally on init. This allows us to fix all drivers in one go, enforced
by compiler error if the parameter is missing.
Fixes: aaa4a221da26 ("event/sw: add new software-only eventdev driver")
Fixes: 46a186b1f0c5 ("event/dsw: add device registration and build system")
Fixes: bbbb929da5e6 ("event/skeleton: add skeleton eventdev driver")
Fixes: 3c7f3dcfb099 ("event/opdl: add PMD main body and helper function")
Fixes: 9caac5dd1e7f ("event/dpaa: introduce PMD")
Fixes: 8a5d7a8ec74b ("event/dpaa2: initialize device")
Fixes: 34498de6000f ("event/octeontx: add octeontx eventdev driver")
