This is a note to let you know that I've just added the patch titled media: rkisp1: Drop IRQF_SHARED to the 5.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: media-rkisp1-drop-irqf_shared.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 6e8369af75340c00335efc1c577a164ca5f3afac Author: Tomi Valkeinen <tomi.valkeinen@xxxxxxxxxxxxxxxx> Date: Thu Dec 7 08:57:45 2023 +0100 media: rkisp1: Drop IRQF_SHARED [ Upstream commit 85d2a31fe4d9be1555f621ead7a520d8791e0f74 ] In all known platforms the ISP has dedicated IRQ lines, but for some reason the driver uses IRQF_SHARED. Supporting IRQF_SHARED properly requires handling interrupts even when our device is disabled, and the driver does not handle this. To avoid adding such code, and to be sure the driver won't accidentally be used in a platform with shared interrupts, let's drop the IRQF_SHARED flag.
