This one needs a fix up due to commit 07d8004d6fb9 ("tpm: add bufsiz
parameter in the .send callback") in 6.17-rc1, as I am seeing the
following error in next-20250912.
drivers/char/tpm/tpm_loongson.c:48:17: error: initialization of 'int (*)(struct tpm_chip *, u8 *, size_t, size_t)' {aka 'int (*)(struct tpm_chip *, unsigned char *, long unsigned int, long unsigned int)'} from incompatible pointer type 'int (*)(struct tpm_chip *, u8 *, size_t)' {aka 'int (*)(struct tpm_chip *, unsigned char *, long unsigned int)'} [-Wincompatible-pointer-types]

Can you squash it or do you want a separate patch?
Cheers,
