Subject: [PATCH 12/12] spi: gpio: Use devm_spi_register_master()
Date: Tue,  2 Apr 2019 21:01:33 -0700	[thread overview]
Message-ID: <20190403040133.1459-13-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20190403040133.1459-1-andrew.smirnov@gmail.com>

Replace spi_bitbang_start() with a combination of spi_bitbang_init()
and devm_spi_register_master() and drop all of the explicit
cleanup-related code that's no longer necessary.
