Subject: [PATCH v4 38/38] videobuf2: use sgtable-based scatterlist wrappers
Date: Tue, 12 May 2020 11:00:58 +0200 [thread overview]
Message-ID: <20200512090058.14910-38-m.szyprowski@samsung.com> (raw)
In-Reply-To: <20200512090058.14910-1-m.szyprowski@samsung.com>
Use recently introduced common wrappers operating directly on the struct
sg_table objects and scatterlist page iterators to make the code a bit
more compact, robust, easier to follow and copy/paste safe.
No functional change, because the code already properly did all the
scaterlist related calls.
