Ruoyu Wang 264216889d tpm: st33zp24: Validate locality read result ... check_locality() treats every nonzero transport return as success. SPI errors remain negative, while the I2C path can convert a negative write error through its byte-sized status variable. Either result is nonzero even though the TPM_ACCESS byte can remain unwritten, so indeterminate ACTIVE_LOCALITY and VALID bits can falsely report an active locality. Require recv() to return exactly the requested byte before examining TPM_ACCESS. Transport errors and short reads now report an inactive locality, while successful reads retain the existing behavior. This issue was found by a static analysis checker and confirmed by manual source review.
