watchdog: Fix null pointer dereference while accessing rdc321x platform_data

2011-01-07T21:58:43+00:00

commit 3b3c1f24e96c411a95daabb6af9e09c5381f713b upstream.

rdc321x-wdt currently fetches its driver specific data by using the
platform_device->platform_data pointer, this is wrong because the mfd
device which registers our platform_device has been added using
mfd_add_device() which sets the platform_device->driver_data pointer
instead.

watchdog: ts72xx_wdt: disable watchdog at probe

2010-09-15T18:43:52+00:00

Since it may be already enabled by bootloader or some other utility. This patch
makes sure that the watchdog is disabled before any userspace daemon opens the
device. It is also required by the watchdog API.

watchdog: sb_wdog: release irq and reboot notifier in error path and module_exit()

2010-09-15T18:43:47+00:00

irq and reboot notifier are acquired in module_init() but never released.
They should be released correctly, otherwise reloading the module or error
during module_init() will cause a problem.

watchdog: hpwdt (12/12): Make NMI decoding a compile-time option

2010-08-13T20:54:53+00:00

hpwdt is quite functional without the NMI decoding feature.
This change lets users disable the NMI portion at compile-time
via the new HPWDT_NMI_DECODING config option.

watchdog: hpwdt (11/12): move NMI-decoding init and exit to seperate functions

2010-08-13T20:54:52+00:00

Move NMI-decoding initialisation and exit code to seperate functions so that
we can ifdef-out parts of it in the future.

Also, this is for a device, so let's use dev_info instead of printk.

watchdog: hpwdt (10/12): Use "decoding" instead of "sourcing"

2010-08-13T20:54:50+00:00

The term "decoding" more clearly explains what hpwdt is doing. It isn't
just finding the source of the interrupt, but rather aids in decoding what
the interrupt means.

Let applications use this entire range.
