[PATCH V2 47/63] clocksource/drivers/timer-stm32: Convert init function to return error

2016-06-16 23:27 GMT+02:00 Daniel Lezcano [off-list ref]:

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.
