This is a note to let you know that I've just added the patch titled wifi: p54: Use IRQF_NO_AUTOEN flag in request_irq() to the 6.6-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: wifi-p54-use-irqf_no_autoen-flag-in-request_irq.patch and it can be found in the queue-6.6 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 3292edf24647dfb8bd9992bfac330add208e3e91 Author: Jinjie Ruan <ruanjinjie@xxxxxxxxxx> Date: Tue Sep 10 20:43:12 2024 +0800 wifi: p54: Use IRQF_NO_AUTOEN flag in request_irq() [ Upstream commit bcd1371bd85e560ccc9159b7747f94bfe43b77a6 ] disable_irq() after request_irq() still has a time gap in which interrupts can come. request_irq() with IRQF_NO_AUTOEN flag will disable IRQ auto-enable when request IRQ.
