Subject: [PATCH 08/20] phy: qcom-qmp-combo: clean up status polling
Date: Wed, 12 Oct 2022 10:49:50 +0200	[thread overview]
Message-ID: <20221012085002.24099-8-johan+linaro@kernel.org> (raw)
In-Reply-To: <20221012085002.24099-1-johan+linaro@kernel.org>

Clean up the PHY status polling by dropping the configuration mask which
is no longer needed since the QMP driver split.
