-Subject: watchdog: Create watchdog device in watchdog_dev.c
-
-The watchdog character device is currently created in watchdog_dev.c,
-and the watchdog device in watchdog_core.c. This results in
-cross-dependencies, since device creation needs to know the watchdog
-character device number as well as the watchdog class, both of which
-reside in watchdog_dev.c.
-
-Create the watchdog device in watchdog_dev.c to simplify the code.
-
-Inspired by earlier patch set from Damien Riegel.
