[PATCH v4 17/45] media: sun6i-csi: Rename sun6i_video to sun6i_csi_capture

Paul Kocialkowski
2022-04-15T15:41:08Z

In an effort to distinguish between the core csi engine (to be
represented as the bridge) and the dma engine (the capture video
device), rename the video component to capture, with the appropriate
prefix. No functional change intended.
