Subject: [PATCH] tpm/ppi: Constify static struct attribute_group
Date: Thu, 4 Feb 2021 22:54:27 +0100 [thread overview]
Message-ID: <20210204215427.49047-1-rikard.falkeborn@gmail.com> (raw)
The only usage of ppi_attr_grp is to put its address in an array of
pointers to const struct attribute_group. Make it const to allow the
compiler to put it in read-only memory.
