+Subject: [PATCH] MIPS: ath79: use dynamically allocated USB platform devices
+
+commit 90a938d1add4859ad3e43c3dd5ee54bd0627e42d upstream.
+
+The current code uses static resources and static platform
+device instances for the possible USB controllers in the
+system. These static variables contains initial values which
+leads to data segment pollution.
+
+Remove the static variables and use dynamically allocated
+structures instead.
