As a prerequisite, it adds a "shutdown" method to "struct class". Since this bug can cause users to be locked out of their TPMs, I'd like this patch included in at least 4.4 and 4.9. 4.1 is nice-to-have but not essential. gregkh Acked the proposal for stable in v3 of this patch. drivers/base/core.c | 6 +++++- drivers/char/tpm/tpm-chip.c | 34 ++++++++++++++++++++++++++++++++++ drivers/char/tpm/tpm-sysfs.c | 3 +++ include/linux/device.h | 2 ++ 4 files changed, 44 insertions(+), 1 deletion(-) ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot
