Subject: [PATCH v2 0/4] libstub,tpm: fix small bugs and improve error reporting
The efi/tpm code has a number of small signed/unsigned bugs and
inaccuracies are prone to cause further bugs in a difficult to
debug manner. For example, there is a signed/unsigned mismatch
in efi/tpm.c that can lead to calling memblock_reserve on a range
with an effectively negative length.
Additionally, there are silently ignored error conditions may
result in undefined behavior. Address these.
