tpm, tpm_tis: Claim locality before writing TPM_INT_ENABLE register
stable inclusion from stable-v5.10.180 commit cbb1dd27058eac7327a0c67e450fcac5b828d29d category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8DDFN Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=cbb1dd27058eac7327a0c67e450fcac5b828d29d -------------------------------- [ Upstream commit 282657a8 ] In disable_interrupts() the TPM_GLOBAL_INT_ENABLE bit is unset in the TPM_INT_ENABLE register to shut the interrupts off. However modifying the register is only possible with a held locality. So claim the locality before disable_interrupts() is called. Signed-off-by:Lino Sanfilippo <l.sanfilippo@kunbus.com> Tested-by:
