This was was in next up to next-20230717, it's not included in
next-20230718 any more. The branch pulled into next from 

	git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd.git#next

changed from 0ec1b5bea32bce719ebdab253462f9c9cb0aca3e to
481c2d14627de8ecbb54dd125466e4b4a5069b47. This is a rebase to v6.5-rc2
dropping some more patches:

	$ git log --oneline 481c2d14627de8ecbb54dd125466e4b4a5069b47...0ec1b5bea32bce719ebdab253462f9c9cb0aca3e --cherry-pick --right-only
	5a29fb0d959a tpm: make all 'class' structures const
	17222dfebab1 tpm: remove redundant variable len
	dfd6ecc2066c tpm_tis: Resend command to recover from data transfer errors
	8458b36c647c tpm_tis: Use responseRetry to recover from data transfer errors
	a5dd583aa98b tpm_tis: Move CRC check to generic send routine
	126f3df1f03c tpm_tis: Explicitly check for error code
	dfba6d4ad558 tpm: Switch i2c drivers back to use .probe()
	bed72785706c tpm_tis-spi: Add hardware wait polling
	2afb9c102761 integrity: Enforce digitalSignature usage in the ima and evm keyrings
	0d8f1c250285 KEYS: DigitalSignature link restriction
	41e4e488742e KEYS: Replace all non-returning strlcpy with strscpy
	e2e51b64f0c8 security: keys: perform capable check only on privileged operations

These all apply just fine on top of next-20230718, so I wonder what made
you drop them. Can you please reapply at least dfba6d4ad558?

Best regards
Uwe
