The i2c driver can run into driver dependency issues if its loaded before a clock driver it depends on. Therefore, EPROBE_DEFER may be returned by devm_clk_get and should be returned in probe to allow the kernel to reprobe the driver at a later time. This patch allows the error value returned by devm_clk_get to be passed through and not overwritten.
