Subject: [PATCH v8 09/19] dmaengine: tegra-apb: Remove unneeded initialization of tdc->config_init
Date: Sun,  9 Feb 2020 19:33:46 +0300	[thread overview]
Message-ID: <20200209163356.6439-10-digetx@gmail.com> (raw)
In-Reply-To: <20200209163356.6439-1-digetx@gmail.com>

There is no need to re-initialize the already initialized variables.
The tdc->config_init=false after driver's probe and after channel's
freeing, so there is no need to re-initialize it on the channel's
allocation.
