From 9a5f91c78abc8985baff89563992be3644f861b0 Mon Sep 17 00:00:00 2001 From: Harvey Yang Date: Tue, 22 Oct 2024 07:43:43 +0000 Subject: libcamera: software_isp: Refactor SoftwareIsp to use DmaBufAllocator::exportBuffers As the helper function DmaBufAllocator::exportBuffers is added, we can avoid some code duplication in SoftwareIsp as well.
