parport: fix a kernel-doc markup

2021-01-21T21:06:00+00:00

The kernel-doc markup inside share.c is actually for __parport_register_driver. The actual goal seems to be to document parport_register_driver(). So, fix the existing markup and add a new one.

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. Signed-off-by: Sudip Mukherjee Link: https://lore.kernel.org/r/20200403134325.11523-10-sudipm.mukherjee@gmail.com Signed-off-by: Greg Kroah-Hartman

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.

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 get_lowlevel_driver+0x28/0x41 [parport] __parport_register_driver+0x39/0x1f4 [parport] daisy_drv_init+0x31/0x4f [parport] parport_bus_init+0x5d/0x7b [parport] parport_default_proc_register+0x26/0x1000 [parport] do_one_initcall+0xc2/0x1e0 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().
