Hi I forgot apply this before that commit:

tpm: Fix some name collisions with drivers/char/tpm.h

* Rename TPM_BUFSIZE defined in drivers/char/tpm/st33zp24/st33zp24.h to
  ST33ZP24_BUFSIZE.
* Rename TPM_BUFSIZE defined in drivers/char/tpm/tpm_i2c_infineon.c to
  TPM_I2C_INFINEON_BUFSIZE.
* Rename TPM_RETRY in tpm_i2c_nuvoton to TPM_I2C_RETRIES.
* Remove TPM_HEADER_SIZE from tpm_i2c_nuvoton.
