A pointer to at91wdt_probe is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded. Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.
An alternative to this patch is using platform_driver_probe instead of
platform_driver_register plus removing the pointer to the probe function
from the struct platform_driver.

The recently merged AT91SAM9 watchdog driver uses the
AT91SAM9X_WATCHDOG config variable, whereas the original version of
the driver (and the platform support code) used AT91SAM9_WATCHDOG.
This causes the watchdog platform_device to never be registered, and
therefore the driver not to be initialized.
This patch:
- updates the platform support code to use AT91SAM9X_WATCHDOG.
- includes <linux/io.h> to fix compile error (same fix as was applied
to at91rm9200_wdt.c)
- fixes comment regarding watchdog clock-rates in at91rm9200.

This brings the watchdog drivers into line with coding style.
This patch takes cares of the indentation as described in chapter 1.
Main changes:
* Re-structure the ioctl switch call for all drivers as follows:
switch (cmd) {
case WDIOC_GETSUPPORT:
case WDIOC_GETSTATUS:
case WDIOC_GETBOOTSTATUS:
case WDIOC_GETTEMP:
case WDIOC_SETOPTIONS:
case WDIOC_KEEPALIVE:
case WDIOC_SETTIMEOUT:
case WDIOC_GETTIMEOUT:
case WDIOC_GETTIMELEFT:
default:
}
This to make the migration from the drivers to the uniform watchdog
device driver easier in the future.

Since 43cc71eed1, the platform modalias is
prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable watchdog
drivers, to re-enable auto loading.

remove asm/bitops.h includes
including asm/bitops directly may cause compile errors. don't include it
and include linux/bitops instead. next patch will deny including asm header
directly.
