[PATCH v2 0/3] Fix a lockdep complaint related to USB role switching

[Bart Van Assche <bvanassche@acm.org>]

Hi Greg,

This patch series suppresses a lockdep complaint about recursive locking
that is triggered by switching USB roles. Please consider this patch series
for the next merge window.

Thanks,

Bart.

Changes compared to v1:
 - Added two patches. One that combines the two mutex_init() definitions and
   another patch that introduces mutex_init_with_key().
 - Changed patch 3/3 such that it uses mutex_init_with_key(). Added Amit's
   Signed-off-by.

Bart Van Assche (3):
  locking/mutex: Define mutex_init() once
  locking/mutex: Introduce mutex_init_with_key()
  usb: roles: Fix a false positive recursive locking complaint
