Subject: [PATCH 2/2] tpm: do not ignore memblock_reserve return value
Date: Fri, 30 Aug 2024 09:23:03 -0400 [thread overview]
Message-ID: <20240830132303.6665-2-gourry@gourry.net> (raw)
In-Reply-To: <20240830132303.6665-1-gourry@gourry.net>
tpm code currently ignores a relevant failure case silently.
Add an error to make this failure non-silent.
