* watchdog: Get rid of MODULE_ALIAS_MISCDEV statementsJean Delvare2013-11-171-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I just can't find any value in MODULE_ALIAS_MISCDEV(WATCHDOG_MINOR) and MODULE_ALIAS_MISCDEV(TEMP_MINOR) statements. Either the device is enumerated and the driver already has a module alias (e.g. PCI, USB etc.) that will get the right driver loaded automatically. Or the device is not enumerated and loading its driver will lead to more or less intrusive hardware poking. Such hardware poking should be limited to a bare minimum, so the user should really decide which drivers should be tried and in what order. Trying them all in arbitrary order can't do any good. On top of that, loading that many drivers at once bloats the kernel log. Also many drivers will stay loaded afterward, bloating the output of "lsmod" and wasting memory. Some modules (cs5535_mfgpt which gets loaded as a dependency) can't even be unloaded! If defining char-major-10-130 is needed then it should happen in user-space.

* watchdog: Remove redundant of_match_ptrSachin Kamat2013-11-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | of_match_ptr() is a macro used to avoid undefined reference error if CONFIG_OF is used to selectively compile in or out the data structure. It is defined as follows: #ifdef CONFIG_OF #define of_match_ptr(ptr) ptr #else #define of_match_ptr(ptr) NULL #endif In the case of this series, none of the drivers use CONFIG_OF macro to compile out the data structure (i.e., the data structure is always defined). Hence the use of of_match_ptr() does not make any sense. Thus removing it to make the code look simpler for readability.

* [WATCHDOG] at91rm9200_wdt.c: move probe function to .devinit.textUwe Kleine-König2009-04-081-3/+3
| | | | | | | | | | | | | | | | | | | | | 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.

* [ARM] 5390/1: AT91: Watchdog fixesAndrew Victor2009-02-141-2/+2
| | | | | | | | | | | | | | | | | 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.

| * [WATCHDOG] Coding style - Indentation - part 2Wim Van Sebroeck2008-08-061-14/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
