[PATCH 4.10 030/129] spi: armada-3700: Remove spi_master_put in a3700_spi_remove()

Show all headers | View raw

4.10-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Wei Yongjun <weiyongjun1@huawei.com>

commit e92f0051c0c65d7bee989884a233cfcd80303bdf upstream.

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")
