Jarkko Sakkinen fbefc2d289 tpm, tpm_tis: Decorate tpm_get_timeouts() with request_locality() ... commit a5665ec2affdba21bff3b0d4d3aed83b3951e8ff upstream. This is shown with Samsung Chromebook Pro (Caroline) with TPM 1.2 (SLB 9670): [ 4.324298] TPM returned invalid status [ 4.324806] WARNING: CPU: 2 PID: 1 at drivers/char/tpm/tpm_tis_core.c:275 tpm_tis_status+0x86/0x8f Background ========== TCG PC Client Platform TPM Profile (PTP) Specification, paragraph 6.1 FIFO Interface Locality Usage per Register, Table 39 Register Behavior Based on Locality Setting for FIFO - a read attempt to TPM_STS_x Registers returns 0xFF in case of lack of locality. The fix ======= Decorate tpm_get_timeouts() with request_locality() and release_locality().
