Hi friends,
I can not use this function in my kernel, I have to use the functions
of kernel timer, I made a driver but he is not printing on the screen
after the time (jiffies + 5*HZ)five seconds.

#include <linux/timer.h>
void hello_print(unsigned long ptr ){
                                printk("Hello World!!\n");
                }
static void TIMER(){
                struct timer_list hello_timer;
                init_timer(&hello_timer);
                hello_timer.function = hello_print;
                hello_timer.data = (unsigned long)NULL;
                hello_timer.expires=jiffies + 5*HZ;  //5 seconds
                printk("Timer in action\n");
                add_timer(&hello_timer);
                del_timer_sync(&hello_timer);

}

When i use this function in my driver, this soluction isn't working.
Somebody could help me with this, because i need to use this function
in my PWM driver. I need one example with this function.

Thanks,
Regards Thiago...
