Subject: [PATCH] iio: adc: exynos: Simplify Exynos7-specific init
Date: Mon, 11 May 2020 10:33:48 +0200	[thread overview]
Message-ID: <20200511083348.7577-1-krzk@kernel.org> (raw)

The Exynos7-specific code bits in ADC driver do not play with PHY:
the field exynos_adc_data.needs_adc_phy is not set in exynos7_adc_data
instance.  Therefore the initialization code does not have to check if
it is true.

Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

Only build tested.
