I'm all for fixing memory leaks, but freeing a block while it is still
being used is a recipe for hard-to-debug kernel exceptions.
1) There is already a vchi method for freeing the instance, so use it.
2) Only call it on error, and then only before initted is false.

In function xfs_test_remount_options(), kfree() is used to free memory
allocated by kmem_zalloc(). But it is better to use kmem_free().

This allows us to use kernel core functionality (e.g. cma) for ITS

In function kexec_calculate_store_digests(), kfree() is used to free
memory allocated by crypto_alloc_shash(). It is better to use function
crypto_free_shash(), which also zeroizes the memory to be freed.

Stefan,
Still on the vTPM requirements, could you help answering the following
questions?
1. Where will the boot measurements be stored? What is the integrity
measurement domain for this vTPM? The current proposal is that the
vTPM would be used for the container (or namespace) files/inodes.

In function xen_9pfs_front_probe(), variable len is checked against 0 to
to check the case that xenbus_read() fails. However, xenbus_read() may
return an ERR_PTR pointer even aften assigning a non-zero value to len.
As a result, the check of len cannot prevent from accessing bad memory.

Use standard V4L2 control to get pixel clock rate from a sensor
linked in the media controller pipeline. Then calculate clock
rates on CSIPHY, CSID and VFE to use the lowest possible.
If the currnet pixel clock rate of the sensor cannot be read then
use the highest possible. This case covers also
