Description niejianglei2021@163.com 2022-07-11 07:56:24 UTC 
bhnd_pmu_core_attach() allocates resource with bhnd_alloc_resource_any()
and bhnd_alloc_pmu(). When some error occurs in this funciton, some
relevant resource is not released, which will lead to a resource leak.

We should release the relevant relevant with bhnd_release_resource() and
bhnd_release_pmu() on the error path to avoid the resource leak.
