+Subject: [PATCH] tpm: use struct tpm_chip for tpm_chip_find_get()
+
+Device number (the character device index) is not a stable identifier
+for a TPM chip. That is the reason why every call site passes
+TPM_ANY_NUM to tpm_chip_find_get().
+
+This commit changes the API in a way that instead a struct tpm_chip
+instance is given and NULL means the default chip. In addition, this
+commit refines the documentation to be up to date with the
+implementation.
