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 correctlyor
- 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.Signed-off-by: Daniel Lezcano

Currently, the clksrc-probe is not able to handle any error from the init
functions. There are different issues with the current code:
- the code is duplicated in the init functions by writing error
- every driver tends to panic in its own init function
- counting the number of clocksources is not reliableThis patch adds another table to store the functions returning an error.
The table is temporary while we convert all the drivers to return an error
and will disappear.Signed-off-by: Daniel Lezcano

The macro OF_DECLARE_1 expect a void (*func)(struct device_node *) while the
OF_DECLARE_2 expect a int (*func)(struct device_node *, struct device_node *).The second one allows to pass an init function returning a value, which make
possible to call the functions in the table and check the return value in order
to catch at a higher level the errors and handle them from there instead of
doing a panic in each driver (well at least this is the case for the clkevt).Unfortunately the OF_DECLARE_1 does not allow that and that lead to some code
duplication and crappyness in the drivers.The OF_DECLARE_1 is used by all the clk drivers and the clocksource/clockevent
drivers. It is not possible to do the change in one shot as we have to change
all the init functions.The OF_DECLARE_2 specifies an init function prototype with two parameters with
the node and its parent. The latter won't be used, ever, in the timer drivers.Introduce a OF_DECLARE_1_RET macro to be used, and hopefully we can smoothly
and iteratively change the users of OF_DECLARE_1 to use the new macro instead.Signed-off-by: Daniel Lezcano
