Building with gcc-10 causes a harmless warning about a section mismatch:

WARNING: modpost: vmlinux.o(.text.unlikely+0x5e191): Section mismatch in reference from the function tpm2_calc_event_log_size() to the function .init.text:early_memunmap()
The function tpm2_calc_event_log_size() references
the function __init early_memunmap().
This is often because tpm2_calc_event_log_size lacks a __init
annotation or the annotation of early_memunmap is wrong.

Add the missing annotation.

Fixes: e658c82be556 ("efi/tpm: Only set 'efi_tpm_final_log_size' after successful event log parsing")
Signed-off-by: Arnd Bergmann <arnd@xxxxxxxx>

Minor thing, but should the Fixes be c46f3405692d ("tpm: Reserve the TPM final events table")? Or what am I missing
about e658c82be556 that causes this? Just trying to understand what I did. :)

Jerry
