Subject: [PATCH 1/6] spi: sprd: adi: Remove redundant address bits setting
Date: Fri, 26 Jul 2019 15:20:48 +0800	[thread overview]
Message-ID: <3cb57b8aadb7747a9f833e9b4fe8596ba738d9f6.1564125131.git.baolin.wang@linaro.org> (raw)

In-Reply-To: <cover.1564125131.git.baolin.wang@linaro.org>

The ADI default transfer address bits is 12bit on Spreadtrum SC9860
platform, thus there is no need to set again, remove it.
