Subject: [PATCH 1/1] UBSAN: fix typo in format string
Date: Sat, 30 Jul 2016 10:30:10 +0200
Message-ID: <> (raw)
In-Reply-To: <>

handle_object_size_mismatch() used %pk to format a kernel pointer with
pr_err().  This seemed to be a misspelling for %pK, but using this to
format a kernel pointer does not make much sence here.

Therefore use %p instead, like in handle_missaligned_access().
