Subject: dmaengine: ste_dma40: don't check for pm_runtime_suspended()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=42365cf0fa19473dde5fe226b0e7e9ab8ea18af8;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

dmaengine: ste_dma40: don't check for pm_runtime_suspended()

The check for runtime suspend is not needed during a regular suspend, as
the framework takes care of this.  This fixes the issue of DMA driver
not letting the system to go to deepsleep in the first attempt.
