Subject: [PATCH 1/3] spi: s3c64xx: simplify getting of_device_id match data
Date: Wed, 14 Apr 2021 22:33:41 +0200
Message-ID: <20210414203343.203119-1-krzysztof.kozlowski@canonical.com> (raw)

Use of_device_get_match_data() to make the code slightly smaller and to
remove the of_device_id table forward declaration.
