watchdog: sp5100_tco.c: Check if firmware has set correct value in tcobase.

commit 90d241edd13bdeef70f264b569f7e150bf23621e upstream. Stefano found SP5100 TCO watchdog driver using wrong address. [ 9.148536] SP5100 TCO timer: SP5100 TCO WatchDog Timer Driver v0.01 [ 9.148628] DEBUG __ioremap_caller WARNING address=b8fe00 size=8 valid=1 reserved=1 and e820 said that range is RAM. We should check if we can use that reading out. BIOS could just program wrong address there.

watchdog: Convert release_resource to release_region/release_mem_region

2011-04-14T20:02:04+00:00

commit f712eacf02ecfbf4f1686addb8c569841549b0b7 upstream. Request_mem_region should be used with release_mem_region, not release_resource. In pnx4008_wdt.c, a missing clk_put is added as well. The semantic match that finds the first problem is as follows: (http://coccinelle.lip6.fr/) // @@ expression x,E; @@ *x = request_mem_region(...) ... when != release_mem_region(x) when != x = E * release_resource(x); // Signed-off-by: Julia Lawall Signed-off-by: Wim Van Sebroeck Signed-off-by: Greg Kroah-Hartman

watchdog: hpwdt: eliminate section mismatch warning

2011-03-14T10:44:31+00:00

hpwdt_init_nmi_decoding() is called in hpwdt_init_one error handling, thus remove the __devexit annotation of hpwdt_exit_nmi_decoding(). This patch fixes below warning: WARNING: drivers/watchdog/hpwdt.o(.devinit.text+0x36f): Section mismatch in reference from the function hpwdt_init_one() to the function .devexit.text:hpwdt_exit_nmi_decoding() The function __devinit hpwdt_init_one() references a function __devexit hpwdt_exit_nmi_decoding(). This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __devexit annotation of hpwdt_exit_nmi_decoding() so it may be used outside an exit section.

watchdog: sbc_fitpc2_wdt, fix crash on systems without DMI_BOARD_NAME

2011-03-09T21:33:37+00:00

Some systems don't provide DMI_BOARD_NAME in their DMI tables. Avoid crash in such situations in fitpc2_wdt_init. The fix is to check if the dmi_get_system_info return value is NULL.
