Subject: [RFC PATCH 04/14] iio: core,buffer: wrap iio_buffer_put() call into iio_buffers_put()
Date: Fri, 8 May 2020 16:53:38 +0300 [thread overview]
Message-ID: <20200508135348.15229-5-alexandru.ardelean@analog.com> (raw)
In-Reply-To: <20200508135348.15229-1-alexandru.ardelean@analog.com>
The name (and the wrapper) seems superfluous now, but when more buffers
will be attached to the IIO device this will be a bit more useful.
