Subject: [PATCH 9/9] riscv: call pm_power_off from machine_halt / machine_power_off
Date: Thu, 11 Apr 2019 13:56:23 +0200 [thread overview]
Message-ID: <20190411115623.5749-10-hch@lst.de> (raw)
In-Reply-To: <20190411115623.5749-1-hch@lst.de>
This way any override of pm_power_off also affects the halt path and
we don't need additional infrastructure for it.
Also remove the pm_power_off export - at least for now we don't have
any modular drivers overriding it.
