From a107d643b2a3382e0a2d2c4ef08bf8c6bff4561d Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen tomi.valkeinen@ideasonboard.com Date: Mon, 18 Dec 2023 08:54:00 +0100 Subject: [PATCH] media: Revert "media: rkisp1: Drop IRQF_SHARED"

This reverts commit 85d2a31fe4d9be1555f621ead7a520d8791e0f74.

The rkisp1 does share interrupt lines on some platforms, after all. Thus we need to revert this, and implement a fix for the rkisp1 shared irq handling in a follow-up patch.
