Subject: [PATCH 4/6] HSI: omap_ssi: fix removal of port platform device
Date: Sat, 30 Apr 2016 04:09:11 +0200	[thread overview]
Message-ID: <1461982153-19139-5-git-send-email-sre@kernel.org> (raw)
In-Reply-To: <1461982153-19139-1-git-send-email-sre@kernel.org>

This avoids removal of the HSI port device when
only the platform port device should be removed
and clears the POPULATED bit in the DT node, so
that a new platform device is created when the
driver is probed again.
