That doesn't work AT ALL.

You have this duplicated line

-       TPM_CHIP_FLAG_FIRMWARE_UPGRADE  = BIT(7),
+       TPM_CHIP_FLAG_FIRMWARE_UPGRADE          = BIT(7),
+       TPM_CHIP_FLAG_FIRMWARE_UPGRADE          = BIT(7),
+       TPM_CHIP_FLAG_FIRMWARE_UPGRADE          = BIT(7),

in that patch (presumably due to some edit-time fat-fingering), which
causes lots and lots of

  ./include/linux/tpm.h:285:9: error: redeclaration of enumerator
‘TPM_CHIP_FLAG_FIRMWARE_UPGRADE’
    285 |         TPM_CHIP_FLAG_FIRMWARE_UPGRADE          = BIT(7),
        |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  ./include/linux/tpm.h:284:9: note: previous definition of
‘TPM_CHIP_FLAG_FIRMWARE_UPGRADE’ with type ‘int’

  ./include/linux/tpm.h:286:9: error: redeclaration of enumerator

    286 |         TPM_CHIP_FLAG_FIRMWARE_UPGRADE          = BIT(7),
        |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

errors.

While I could easily just remove the duplicated lines in my merge,
that would make things non-bisectable, so I unpulled this instead.
