Subject: [PATCH v7 09/19] dmaengine: tegra-apb: Remove unneeded initialization of tdc->config_init
Date: Mon, 3 Feb 2020 01:28:44 +0300 [thread overview]
Message-ID: <20200202222854.18409-10-digetx@gmail.com> (raw)
In-Reply-To: <20200202222854.18409-1-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.
