-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.
