Same as today, it gets ignored. This is not uncommon among drivers,
there are just too many things to check. On many platforms the
clk_enable() just cannot return anything but 0,
For example in the SPEAr ultimately a gate clock seems to
be registered for this clock and the code handling enable
looks like this (drivers/clk/clk-gate.c):
static int clk_gate_enable(struct clk_hw *hw)
{
clk_gate_endisable(hw, 1);
return 0;
}
