-Subject: [PATCH 026/182] pinctrl: msm: Silence recursive lockdep warning
-
-If a driver calls enable_irq_wake() on a gpio turned interrupt
-from the msm pinctrl driver we'll get a lockdep warning like so:
-
-=============================================
-[ INFO: possible recursive locking detected ]
-3.14.0-rc3 #2 Not tainted
----------------------------------------------
-modprobe/52 is trying to acquire lock:
- (&irq_desc_lock_class){-.....}, at: [<c026aea0>] __irq_get_desc_lock+0x48/0x88
-
-but task is already holding lock:
- (&irq_desc_lock_class){-.....}, at: [<c026aea0>] __irq_get_desc_lock+0x48/0x88
-
-other info that might help us debug this:
- Possible unsafe locking scenario:
-
-       CPU0
-       ----
-  lock(&irq_desc_lock_class);
-  lock(&irq_desc_lock_class);
-
- *** DEADLOCK ***
-
- May be due to missing lock nesting notation
-
-4 locks held by modprobe/52:
- #0:  (&__lockdep_no_validate__){......}, at: [<c04f2864>] __driver_attach+0x48/0x98
- #1:  (&__lockdep_no_validate__){......}, at: [<c04f2874>] __driver_attach+0x58/0x98
- #2:  (&irq_desc_lock_class){-.....}, at: [<c026aea0>] __irq_get_desc_lock+0x48/0x88
- #3:  (&(&pctrl->lock)->rlock){......}, at: [<c04bb4b8>] msm_gpio_irq_set_wake+0x20/0xa8
-
-Silence it by putting the gpios into their own lock class.
