+Subject: [PATCH] MIPS: ath79: use dynamically allocated watchdog device
+
+commit 0f2ad9ed7c6fecb008372e8a709595a2a21059aa upstream.
+
+Remove the static watchdog device variable and use
+the 'platform_device_register_simple' helper to
+allocate and register the device in one step.
+
+This allows us to save a few bytes in the kernel image.
