Subject: [PATCH kcsan 16/19] kcsan: Use pr_fmt for consistency
Date: Mon, 31 Aug 2020 11:18:02 -0700 [thread overview]
Message-ID: <20200831181805.1833-16-paulmck@kernel.org> (raw)
In-Reply-To: <20200831181715.GA1530@paulmck-ThinkPad-P72>
From: Marco Elver <elver@google.com>
Use the same pr_fmt throughout for consistency. [ The only exception is
report.c, where the format must be kept precisely as-is. ]
