drivers/pps: use surrounding "if PPS" to remove numerous dependency checks

2017-09-09T01:26:51+00:00

Adding high-level "if PPS" makes lower-level dependency tests superfluous. Link: http://lkml.kernel.org/r/alpine.LFD.2.20.1708261050500.8156@localhost.localdomain Signed-off-by: Robert P. J. Day Acked-by: Rodolfo Giometti Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers: pps: Make PPS into a menuconfig to ease disabling

2017-05-18T14:59:06+00:00

So that there's no need to get into the submenu to disable all related config entries. The BROKEN PPS_GENERATOR_PARPORT now also depends on PPS Signed-off-by: Vincent Legoll Acked-by: Rodolfo Giometti Signed-off-by: Greg Kroah-Hartman

pps: do not crash when failed to register

2016-07-23T01:25:54+00:00

With this command sequence: modprobe plip modprobe pps_parport rmmod pps_parport the partport_pps modules causes this crash: BUG: unable to handle kernel NULL pointer dereference at (null) IP: parport_detach+0x1d/0x60 [pps_parport] Oops: 0000 [#1] SMP ... Call Trace: parport_unregister_driver+0x65/0xc0 [parport] SyS_delete_module+0x187/0x210 The sequence that builds up to this is: 1) plip is loaded and takes the parport device for exclusive use: plip0: Parallel port at 0x378, using IRQ 7. 2) pps_parport then fails to grab the device: pps_parport: parallel port PPS client parport0: cannot grant exclusive access for device pps_parport pps_parport: couldn't register with parport0 3) rmmod of pps_parport is then killed because it tries to access pardev->name, but pardev (taken from port->cad) is NULL. So add a check for NULL in the test there too.

pps: clients: drop owner assignment from platform_drivers

2014-10-20T14:21:28+00:00

A platform_driver does not need to set an owner, it will be populated by the driver core. Signed-off-by: Wolfram Sang

drivers/pps/clients/pps-gpio.c: remove redundant of_match_ptr

2013-11-13T03:09:35+00:00

The data structure of_match_ptr() protects is always compiled in. Hence of_match_ptr() is not needed. Signed-off-by: Sachin Kamat Cc: Rodolfo Giometti Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

Remove GENERIC_HARDIRQ config option

2013-09-13T13:09:52+00:00

After the last architecture switched to generic hard irqs the config options HAVE_GENERIC_HARDIRQS & GENERIC_HARDIRQS and the related code for !CONFIG_GENERIC_HARDIRQS can be removed. Signed-off-by: Martin Schwidefsky

drivers/pps/clients/pps-gpio.c: remove unnecessary platform_set_drvdata()

2013-09-11T22:59:34+00:00

The driver core clears the driver data to NULL after device_release or on probe failure. Thus, it is not needed to manually clear the device driver data to NULL. Signed-off-by: Jingoo Han Cc: Rodolfo Giometti Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

pps-gpio: add device-tree binding and support

2013-07-03T23:08:06+00:00

Instead of allocating a struct pps_gpio_platform_data in the DT case, store the necessary information in struct pps_gpio_device_data itself. This avoids an additional allocation and the ifdef. It also gets rid of some indirection. Also use dev_err instead of pr_err in the changed code.
