Subject: [PATCH net v2 1/5] ptp: vmclock: Add .owner to vmclock_miscdev_fops
Date: Fri, 07 Feb 2025 10:39:02 +0100 [thread overview]
Message-ID: <20250207-vmclock-probe-v2-1-bc2fce0bdf07@linutronix.de> (raw)
In-Reply-To: <20250207-vmclock-probe-v2-0-bc2fce0bdf07@linutronix.de>
From: David Woodhouse <dwmw@amazon.co.uk>
Without the .owner field, the module can be unloaded while /dev/vmclock0
is open, leading to an oops.
Fixes: 205032724226 ("ptp: Add support for the AMZNC10C 'vmclock' device")
