Current code checks "clk_delay_cycles > 0" to know whether the optional "mrvl,clk_delay_cycles" is set or not. But of_property_read_u32() doesn't touch clk_delay_cycles if the property is not set. And type of clk_delay_cycles is u32, so we may always set pdata->clk_delay_cycles as a random value. This patch fix this problem by check the return value of of_property_read_u32() to know whether the optional clk-delay-cycles is set or not.
