Subject: [PATCH 10/20] media: atomisp: add debug message to help debugging hmm code
Date: Thu, 28 May 2020 08:14:10 +0200 [thread overview]
Message-ID: <a4b9ab6712e830e101ffa0f16c8bfe933db77bac.1590646166.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1590646166.git.mchehab+huawei@kernel.org>
The hmm code is partially based on a fork from 3.10 code,
and has bugs.
Add debug there to help tracking what happens there.
