Subject: media: aspeed: Fix no complete irq for non-64-aligned width Author: Jammy Huang <[email protected]> Date: Wed Jan 12 07:07:25 2022 +0100 In ast2500, engine will stop occasionally for 1360x768. This is a bug which has been addressed, but the workaround is specific for 1680 only. Here we make it more complete.
