[PATCH v2 0/2] watchdog: report all watchdog_ident information via sysfs

From: Thomas Weißschuh
Date: Mon Dec 19 2022 - 16:31:01 EST


This synchronizes the information reported by ioctl and sysfs.
The mismatch is confusing because "wdctl" from util-linux uses the ioctl
when used with root privileges and sysfs without.
