Dropped it. Breaks the compilation:

ld: drivers/char/tpm/tpm_tis_spi_cr50.o:(.rodata+0x10): undefined reference to `tpm_tis_spi_read16'
ld: drivers/char/tpm/tpm_tis_spi_cr50.o:(.rodata+0x18): undefined reference to `tpm_tis_spi_read32'
ld: drivers/char/tpm/tpm_tis_spi_cr50.o:(.rodata+0x20): undefined reference to `tpm_tis_spi_write32'

Please fix this issue in the next version of the patch and remove my
reviewed-by. I will have to re-review the patch.
