parport: remove unused parport_register_device()

2020-04-23T15:05:39+00:00

All the drivers that are using parallel port has been converted to use
the new device model api, and parport_register_device() is no longer
used.

parport: Add comments for parport_register_dev_model()

2020-04-23T15:05:39+00:00

In preparation to remove parport_register_device(), copy the comments
to parport_register_dev_model() and modify the parameters according to
what parport_register_dev_model() has.

parport: daisy: avoid hardcoded name

The daisy device name is hardcoded, define it in the header file and
use it in the code.

Revert "parport: daisy: use new parport device model"

2019-03-25T21:49:00+00:00

This reverts commit 1aec4211204d9463d1fd209eb50453de16254599.

Steven Rostedt reports that it causes a hang at bootup and bisected it
to this commit.

The troigger is apparently a module alias for "parport_lowlevel" that
points to "parport_pc", which causes a hang with

    modprobe -q -- parport_lowlevel

blocking forever with a backtrace like this:

    wait_for_completion_killable+0x1c/0x28
    call_usermodehelper_exec+0xa7/0x108
    __request_module+0x351/0x3d8

    do_init_module+0x50/0x1d4
    load_module+0x1c2e/0x21b3
    sys_init_module+0xef/0x117

Supid says:
 "Due to the new device model daisy driver will now try to find the
  parallel ports while trying to register its driver so that it can bind
  with them. Now, since daisy driver is loaded while parport bus is
  initialising the list of parport is still empty and it tries to load
  the lowlevel driver, which has an alias set to parport_pc, now causes
  a deadlock"

But I don't think the daisy driver should be loaded by the parport
initialization in the first place, so let's revert the whole change.

If the daisy driver can just initialize separately on its own (like a
driver should), instead of hooking into the parport init sequence
directly, this issue probably would go away.

timer: Remove init_timer_on_stack() in favor of timer_setup_on_stack()

2017-10-05T13:01:17+00:00

Remove uses of init_timer_on_stack() with open-coded function and data
assignments that could be expressed using timer_setup_on_stack(). Several
were removed from the stack entirely since there was a one-to-one mapping
of parent structure to timer, those are switched to using timer_setup()
instead. All related callbacks were adjusted to use from_timer().

parport: add device-model to parport subsystem

2015-05-31T22:08:18+00:00

parport subsystem starts using the device-model. Drivers using the
device-model has to define devmodel as true and should register the
device with parport using parport_register_dev_model().

parport: quickfix the proc registration bug

2009-06-02T16:53:22+00:00

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 ...
