Subject: [PATCH v6 12/13] media: i2c: imx214: Fix clock handling on probe
 error or remove

From: André Apitzsch <git@...tzsch.eu>

The driver should disable or unprepare the clock on probe error and on
removing the module.

Remove regulator_bulk_disable(), because it is called by
imx214_power_off().
