Always stop and re-start the scheduler in order to let the scheduler
free up the timedout job in case it got signaled. In case of exec jobs
the job type specific callback will take care to signal all fences and
tear down the channel.

On the Lenovo Yoga Tablet 2 830 / 1050 there are 2 problems:
1. The I2C MIPI sequence elements reference bus 3. ACPI has I2C1 - I2C7
which under Linux become bus 0 - 6. And the MIPI sequence reference
to bus 3 is indented for I2C3 which is bus 2 under Linux.
This leads to errors like the
On the Lenovo Yoga Tab 3 Pro YT3-X90F there are 2 issues with the backlight
