Subject: [PATCH] pstore: Properly assign mem_type property
Date: Thu, 22 Dec 2022 14:10:49 +0100 [thread overview]
Message-ID: <20221222131049.286288-1-luca@osomprivacy.com> (raw)
If mem-type is specified in the device tree
it would end up overriding the record_size
field instead of populating mem_type.
As record_size is currently parsed after the
improper assignment with default size 0 it
continued to work as expected regardless of the
value found in the device tree.
Simply changing the target field of the struct
is enough to get mem-type working as expected.
Fixes: 9d843e8fafc7 ("pstore: Add mem_type property DT parsing support")
