Subject: [PATCH -next] spi: armada-3700: Remove spi_master_put in a3700_spi_remove()
Date: Sun, 5 Feb 2017 15:49:40 +0000 [thread overview]
Message-ID: <20170205154940.965-1-weiyj.lk@gmail.com> (raw)
From: Wei Yongjun <weiyongjun1-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>
The call to spi_master_put() in a3700_spi_remove() is redundant since
the master is registered using devm_spi_register_master() and no
reference hold by using spi_master_get() in a3700_spi_remove().
This is detected by Coccinelle semantic patch.
Fixes: 5762ab71eb24 ("spi: Add support for Armada 3700 SPI Controller")
Signed-off-by: Wei Yongjun <weiyongjun1-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>
