Subject: [PATCH 4/9] mfd: sec: Remove unused irq_base in platform data
Date:   Tue, 20 Apr 2021 19:01:13 +0200
Message-Id: <20210420170118.12788-5-krzysztof.kozlowski@canonical.com>

The 'irq_base' field of platform data structure is not assigned,
therefore its default value of 0 has no impact and can be safely
dropped.
