ima: Fix Kconfig to select TPM 2.0 CRB interface
TPM_CRB driver provides TPM CRB 2.0 support. If it is built as a
module, the TPM chip is registered after IMA init. tpm_pcr_read() in
IMA fails and displays the following message even though eventually
there is a TPM chip on the system.
ima: No TPM chip found, activating TPM-bypass! (rc=-19)
Fix IMA Kconfig to select TPM_CRB so TPM_CRB driver is built in the kernel
and initializes before IMA.
