From fed2e02a1210c42ec5a0b61c6f2cb17e9a2ae632 Mon Sep 17 00:00:00 2001 From: Frank Li Date: Fri, 18 Sep 2026 10:02:21 -0400 Subject: [PATCH] media: m2m-deinterlace: replace direct ->device_prep*() calls with standard DMA engine API DMA engine consumers must not call the channel's device_prep_*() function pointers directly. Use the standard dmaengine wrapper APIs instead.
