[PATCH v2] i2c: imx-lpi2c: add clk_disable_unprepare calls

From: Chuhong Yuan
Date: Sat Nov 02 2019 - 02:22:15 EST


The driver forgets to call clk_disable_unprepare when probe fails
and remove.
Add the two calls to fix the problem.

Changes in v2:
- Adjust the call order to make it consistent in probe failure and
removal.
