* [WATCHDOG] improve machzwd detectionDave Jones2006-10-02
| | | | | | | | | | | | | | | | | On a machine with no machzwd, loading the module prints out.. machzwd: MachZ ZF-Logic Watchdog driver initializing. 0xffff machzwd: Watchdog using action = RESET - the 0xffff printk is unnecessary - 0xffff seems to be 'hardware not present' - fix CodingStyle. (This driver could use some more work here) Signed-off-by: Dave Jones <davej@redhat.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be> Signed-off-by: Andrew Morton <akpm@osdl.org>
* [WATCHDOG] use ENOTTY instead of ENOIOCTLCMD in ioctl()Samuel Tardieu2006-10-02
| | | | | | | | | | | | | Return ENOTTY instead of ENOIOCTLCMD in user-visible ioctl() results The watchdog drivers used to return ENOIOCTLCMD for bad ioctl() commands. ENOIOCTLCMD should not be visible by the user, so use ENOTTY instead.

* [WATCHDOG] s3c24XX nowayoutBen Dooks2006-10-02
| | | | | | | | | | | | | | If the driver is not configured for `no way out`, then the open method should not automatically allow the setting of allow_close to CLOSE_STATE_ALLOW. The setting of allow_close nullifies the use of the magic close via the write path. It means that in the default state, the watchdog will shut-down even if the magic close has not been issued.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We were plagued by our interrupt handler posting a watchdog event which could occur when our adapter was going down in case a late packet arrived just before e1000_down() finished. This caused the watchdog timer to start after the NIC was down and keep rescheduling it every N seconds. Once the driver unloaded it would panic. Signed-off-by: Auke Kok <auke-jan.h.kok@intel.com>
