Outside of the EFI tpm code, the TPM_MEMREMAP()/TPM_MEMUNMAP functions are defined as trivial macros, leading to the mapping_size variable ending up unused: In file included from drivers/char/tpm/tpm-sysfs.c:16: In file included from drivers/char/tpm/tpm.h:28: include/linux/tpm_eventlog.h:167:6: error: variable 'mapping_size' set but not used [-Werror,-Wunused-but-set-variable] 167 | int mapping_size; Turn the stubs into inline functions to avoid this warning.
