![]() The rpmsg_dev_remove() in rpmsg_core is the place for releasing
this default endpoint.
So need to avoid destroying the default endpoint in
rpmsg_chrdev_eptdev_destroy(), this should be the same as
rpmsg_eptdev_release(). Otherwise there will be double destroy
issue that ept->refcount report warning:
refcount_t: underflow; use-after-free.
Call trace:
refcount_warn_saturate+0xf8/0x150
virtio_rpmsg_destroy_ept+0xd4/0xec
rpmsg_dev_remove+0x60/0x70
The issue can be reproduced by stopping remoteproc before
closing the /dev/rpmsgX.
