[PATCH] watchdog: exar: Shorten identity name to fit correctly

[Kees Cook <kees@kernel.org>]

The static initializer for struct watchdog_info::identity is too long
and gets initialized without a trailing NUL byte. Since the length
of "identity" is part of UAPI and tied to ioctls, just shorten
the name of the device. Avoids the warning seen with GCC 15's
-Wunterminated-string-initialization option:

drivers/watchdog/exar_wdt.c:224:27: warning: initializer-string for array of 'unsigned char' truncates NUL terminator but destination lacks 'nonstring' attribute (33 chars into 32 available) [-Wunterminated-string-initialization]
  224 |         .identity       = "Exar/MaxLinear XR28V38x Watchdog",
      |                           ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
