I was looking at Luca's original message where he showed the bug of
-- drivers/char/watchdog/cpu5wdt.c: "cpu5wdt: Unknown symbol
there_is_no_init_MUTEX_LOCKED_for_RT_semaphores") --
Looking into this file the only init_MUTEX_LOCKED that I found was
static int __devinit cpu5wdt_init(void)
{
unsigned int val;
int err;
[...]
/* watchdog reboot? */
val = inb(port + CPU5WDT_STATUS_REG);
val = (val >> 2) & 1;
if ( !val )
printk(KERN_INFO PFX "sorry, was my fault\n");
init_MUTEX_LOCKED(&cpu5wdt_device.stop);
cpu5wdt_device.queue = 0;
clear_bit(0, &cpu5wdt_device.inuse);
Here I see that cpu5wdt_device.stop is being initialized with
init_MUTEX_LOCKED, so that is what I went to fix. I even added the
driver to my config and compiled it before sending it in. I don't have
the device, but the driver compiled :-)
