commit 14a8d4bfc2102f85ce097563d151370c91c1898a upstream.
This patch fixes an issue that the spin_lock_init() is not called for almost all pipes. Otherwise, the lockdep output the following message when we connect a usb cable using g_ncm:
INFO: trying to register non-static key. the code is fine but needs lockdep annotation. turning off the locking correctness validator.
