From fccff5c28a3dbd542103ada013ca06e22ea2575f Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe Date: Sat, 9 Nov 2013 11:17:00 -0700 Subject: [PATCH] tpm: Add missing tpm_do_selftest to ST33 I2C driver commit f07a5e9a331045e976a3d317ba43d14859d9407c upstream. Most device drivers do call 'tpm_do_selftest' which executes a TPM_ContinueSelfTest. tpm_i2c_stm_st33 is just pointlessly different, I think it is bug. These days we have the general assumption that the TPM is usable by the kernel immediately after the driver is finished, so we can no longer defer the mandatory self test to userspace.
