6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
[ Upstream commit c1b9f2c66eed3261db76cccd8a22a9affae8dcbf ]
After a successful vp_legacy_probe() call, vp_legacy_remove() should be
called in the error handling path, as already done in the remove function.
Add the missing call.
Fixes: e85087beedca ("eni_vdpa: add vDPA driver for Alibaba ENI")
