The NULL initialization of the pointers assigned by kzalloc() first is
not necessary, because if the kzalloc() failed, the pointers will be
assigned NULL, otherwise it works as usual. so remove it.

Ther are many pointers assigned first, which need not to be initialized, so
remove the NULL assignment.

There is no need to call the DSSERR() function directly to print
a custom message when handling an error from platform_get_irq() function
as it is going to display an appropriate error message
in case of a failure.
