Subject: Revert "interconnect: Teach lockdep about icc_bw_lock order"
From: Greg Kroah-Hartman <gregkh@xxxxxxxxxxxxxxxxxxx>
This reverts commit 0db211ec0f1d32b93486e8f6565249ad4d1bece5 which is
commit 13619170303878e1dae86d9a58b039475c957fcf upstream.
It is reported to cause boot crashes in Android systems, so revert it
from the stable trees for now.
