parport: fix interruptible_sleep_on race

2014-03-01T00:22:42Z

The interruptible_sleep_on function is can still lead to the deadlock mentioned in the comment above the caller, and we want to remove it soon, so replace it now with the race-free wait_event_interruptible.

parport: make lockdep happy with waitlist_lock

2011-01-26T00:49:59Z

parport_unregister_device() should never be used when interrupts are enabled in hardware and irq handler is registered so there is no need to disable interrupts when using waitlist_lock. But there is no way to explain this subtle semantics to lockdep analyzer. So disable interrupts here too to simplify things. The price is negligible.

parport: quickfix the proc registration bug

2009-06-02T16:53:22Z

Ideally we should have a directory of drivers and a link to the 'active' driver. For now just show the first device which is effectively the existing semantics without a warning. This is an update on the original buggy patch that I then forgot to resubmit. Confusingly it was proposed by Red Hat, written by Etched Pixels fixed and submitted by Intel ...

[PARPORT] Remove unused 'irq' argument from parport irq functions

2007-10-23T23:53:16Z

None of the drivers with a struct pardevice's ->irq_func() hook ever used the 'irq' argument passed to it, so remove it. Signed-off-by: Jeff Garzik

[PARPORT] Kill useful 'irq' arg from parport_{generic_irq,ieee1284_interrupt}

2007-10-23T23:53:15Z

parport_ieee1284_interrupt() was not using its first arg at all. Delete. parport_generic_irq()'s second arg makes its first arg completely redundant. Delete, and use port->irq in the one place where we actually need it. Also, s/__inline__/inline/ to make the code look nicer. Signed-off-by: Jeff Garzik

[PARPORT] Consolidate code copies into a single generic irq handler

2007-10-23T23:53:15Z

Several arches used the exact same code for their parport irq handling. Make that code generic, in parport_irq_handler(). Also, s/__inline__/inline/ in include/linux/parport.h. Signed-off-by: Jeff Garzik

parport->dev driver model support

2007-05-08T18:15:05Z

Currently a parport_driver can't get a handle on the device node for the underlying parport (PNPACPI, PCI, etc). That prevents correct placement of sysfs child nodes, which can affect things like power management. This patch adds a field to "struct parport" pointing to that device node, and updates non-legacy port drivers to initialize that device pointer. That field replaces the analagous PCI-only support in parport_pc.
