[PATCH v2 0/2] thermal: int340x: fix tcc offset on resume

[Antoine Tenart <atenart@kernel.org>]

Hi,

This is a follow-up of [1]. As discussed in the initial thread, the fix
is now split into two commits: the two commits combined are fixing the
issue in a nice way for 5.15, but only the first one is meant to be
applied on stable kernels (to avoid conflicts).

The issue this is fixing is described in patch 1. Tl;dr: a
suspend/resume cycle can end-up in setting a wrong tcc offset value,
which can lead to machines shutting down because of overheating (when
they should not).

I've stripped the Acked-by/Tested-by flags from v1 as the patch was
split. But the end result for 5.15+ kernels should be the same.

Thanks,
Antoine
