Subject: [alsa-devel] [PATCH 07/10] ASoC: jz4740: Use of_device_get_match_data()
Date: Fri,  4 Oct 2019 14:43:31 -0700
Message-ID: <20191004214334.149976-8-swboyd@chromium.org> (raw)
In-Reply-To: <20191004214334.149976-1-swboyd@chromium.org>

This probe function is only called if the device is backed by a DT node,
so switch this call to of_device_get_match_data() to reduce code size
and simplify a bit. This also avoids needing to reference a potentially
undefined variable because of_device_get_match_data() doesn't need to
know anything beyond the struct device to find the match table.
