Merge branch 'next-tpm' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security
Pull TPM updates from James Morris:
"Here are the TPM updates from Jarkko for v4.14, which I've placed in
their own branch (next-tpm). I ended up cherry-picking them as other
changes had been made in Jarkko's branch after he sent me his original
pull request.
I plan on maintaining a separate branch for TPM (and other security
subsystems) from now on.
From Jarkko: 'Not much this time except a few fixes'"
* 'next-tpm' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security:
tpm: ibmvtpm: simplify crq initialization and document crq format
tpm: replace msleep() with usleep_range() in TPM 1.2/2.0 generic drivers
Documentation: tpm: add powered-while-suspended binding documentation
tpm: tpm_crb: constify acpi_device_id.
tpm: vtpm: constify vio_device_id
