Dan Carpenter 43a354a21a clk: at91: remove unnecessary conditions
This code checks "if (parent_hw)" is non-NULL, but then it has more
checks if parent_hw is non-NULL on the lines inside the if statement.
It is a bit confusing.

For the else statement, keep in mind that at the start of the function
we checked:

	if (!(parent_name || parent_hw))
		return ERR_PTR(-EINVAL);

That check ensures that if parent_hw is NULL that means that parent_name
is non-NULL.  At least one must always be non-NULL.  So here again, the
checks inside the if statement can be removed.

In the original code, it was a bit confusing and you could easily get
the impression that "init.num_parents" could be zero.  When we remove
the unnecessary checking it's more obvious that it's always set to 1.
