Subject: [PATCH 1/5] clocksource: exynos_mct: Remove dead code
Date: Fri, 15 Feb 2019 13:52:25 +0100 [thread overview]
Message-ID: <20190215125229.30180-2-m.szyprowski@samsung.com> (raw)
In-Reply-To: <20190215125229.30180-1-m.szyprowski@samsung.com>
Exynos Multi-Core Timer driver is used only on device-tree based
systems, so remove non-dt related code. In case of !CONFIG_OF
the code is anyway equal because of_irq_count() has a stub
returning 0. Device node pointer is always provided when driver
has been probed from device tree.
