Subject: [PATCH v3 3/6] ALSA: hda/tegra: Remove unnecessary null-check from hda_tegra_runtime_resume()
Date: Wed, 20 Jan 2021 03:31:51 +0300 [thread overview]
Message-ID: <20210120003154.26749-4-digetx@gmail.com> (raw)
In-Reply-To: <20210120003154.26749-1-digetx@gmail.com>
The "chip" can't be NULL in hda_tegra_runtime_resume() because code would
crash otherwise. Let's remove the unnecessary check in order to clean up
code a tad.
