Subject: mfd: mxs-lradc: Fix error handling in mxs_lradc_probe()

From: Alexey Khoroshilov <khoroshilov@ispras.ru>


[ Upstream commit 362741a21a5c4b9ee31e75ce28d63c6d238a745c ]

There is the only path, where mxs_lradc_probe() leaves clk undisabled,
since it does return instead of goto err_clk.

Found by Linux Driver Verification project (linuxtesting.org).
