[PATCH -next] CLK: clk-twl6040: fix return value check in twl6040_clk_probe()

[Wei Yongjun]

From: Wei Yongjun <yongjun_wei@xxxxxxxxxxxxxxxxx>

In case of error, the function clk_register() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check
should be replaced with IS_ERR().

dpatch engine is used to auto generate this patch.
