pps: hide more configuration symbols behind CONFIG_PPS

2013-05-01T00:04:08Z

Make CONFIG_PPS_DEBUG and CONFIG_NTP_PPS be hidden if CONFIG_PPS is not selected, so that we are not prompted for these configuration options if CONFIG_PPS is not set. Signed-off-by: Florian Fainelli Cc: Rodolfo Giometti Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

drivers/pps/clients/pps-gpio.c: use devm_kzalloc

2013-02-28T03:10:23Z

devm_kzalloc allocates memory that is released when a driver detaches. This patch uses devm_kzalloc for data that is allocated in the probe function of a platform device and is only freed in the remove function.

pps: Move timestamp read into PPS code proper

2013-02-13T18:13:58Z

The PPS (Pulse-Per-Second) line discipline has developed a number of unhealthy attachments to core tty data and functions, ultimately leading to its breakage. The previous patches fixed the crashing. This one reduces coupling further by eliminating the timestamp parameter from the dcd_change ldisc method. This reduces header file linkage and makes the extension more generic, and the timestamp read is delayed only slightly, from just before the ldisc->ops->dcd_change method call to just after.

PPS is not really the must-have subsystem that warrants crashing the machine if the ldisc interface is broken. Signed-off-by: Peter Hurley Signed-off-by: George Spelvin Acked-by: Rodolfo Giometti Signed-off-by: Greg Kroah-Hartman

pps: Fix a use-after free bug when unregistering a source.

2013-02-13T17:40:35Z

Remove the cdev from the system (with cdev_del) *before* deallocating it (in pps_device_destruct, called via kobject_put from device_destroy). Also prevent deallocating a device with open file handles. A better long-term fix is probably to remove the cdev from the pps_device entirely, and instead have all devices reference one global cdev. Then the deallocation ordering becomes simpler. But that's more complex and invasive change, so we leave that for later.

pps: Use pps_lookup_dev to reduce ldisc coupling

2013-02-13T17:40:35Z

Now that N_TTY uses tty->disc_data for its private data, 'subclass' ldiscs cannot use ->disc_data for their own private data. (This is a regression is v3.8-rc1) Use pps_lookup_dev to associate the tty with the pps source instead. This fixes a crashing regression in 3.8-rc1.
