| |
The init functions do not return any error. They behave as the following:
- panic, thus leading to a kernel crash while another timer may work and make the system boot up correctly
or
- print an error and let the caller unaware if the state of the system
Change that by converting the init functions to return an error conforming to the CLOCKSOURCE_OF_RET prototype.
Proper error handling (rollback, errno value) will be changed later case by case, thus this change just return back an error or success in the init function.
