6.13-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Woodhouse <dwmw@xxxxxxxxxxxx>
commit 7b07b040257c1b658ef3eca86e4b6ae02d65069c upstream.
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")
