Rename the field tpm_processing_cmd to tpm_status in ibmvtpm_dev and set
the TPM_STATUS_BUSY flag while the vTPM is busy processing a command.

Declare this already in the fix, and just leave the rename here.
You mean the fix patch does not use 'true' anymore but uses the
TPM_STATUS_BUSY flag already but the name is still tpm_processing_cmd? And
literally only the renaming of this field is done in the 2nd patch?
I can fixup these patches, and use '1', instead of true. No need to send
new ones.
