There has been a bunch of reports (one from kernel bugzilla linked) reporting that when this commit is applied it causes on some machines boot freezes. Unfortunately hardware where this commit causes a failure is not widely available (only one I'm aware is Lenovo T490), which means we cannot predict yet how long it will take to properly fix tpm_tis interrupt probing. Thus, the least worst short term action is to revert the code to the state before this commit. In long term we need fix the tpm_tis probing code to work on machines that Stefan's fix was supposed to fix.
