Subject: [PATCH] spi: davinci: Remove unneeded NULL checking for dspi and dspi->bitbang.master
Date: Thu, 06 Feb 2014 10:52:21 +0800	[thread overview]
Message-ID: <1391655141.12574.1.camel@phoenix> (raw)

spi_master_get_devdata() never returns NULL when spi_alloc_master() success,
so remove NULL test for dspi.
We have ensured master is not NULL before assigning it to dspi->bitbang.master.
So also remove NULL test for dspi->bitbang.master.
