Subjectlinux-next: build failure after merge of the tpmdd tree
Hi Jarkko,

After merging the tpmdd tree, today's linux-next build (arm
multi_v7_defconfig) failed like this:

include/linux/tpm_eventlog.h: In function '__calc_tpm2_event_size':

Caused by commit

05165bf3d231 ("tpm: Abstract crypto agile event size calculations")

and maybe

cdb75b359079 ("tpm: Reserve the TPM final events table")

I have used the tmpdd tree from next-20190415 for today.
