Subject: [PATCH V3] spi: sun4i: disable clocks in the remove function
Date: Thu,  7 Dec 2017 16:20:14 +0900	[thread overview]
Message-ID: <1512631227-27334-1-git-send-email-takuo.koguchi.sw@hitachi.com> (raw)
In-Reply-To: <20171206152005.yfbyylu6tbe5gnnv@flea.lan>

mclk and hclk need to be disabled. Since pm_runtime_disable does
not disable the clocks, use pm_runtime_force_suspend instead.
