Subject: [PATCH] drivers: watchdog: constify watchdog_info structures
Declare watchdog_info structures as const as they are only stored in the
info field of watchdog_device structures. This field is of type const
struct watchdog_info *, so watchdog_info structures having this property
can be declared const too.
Done using Coccinelle:
