On the current master I get: Applying: switchdev: mrp: Extend ring_role_mrp and in_role_mrp Applying: bridge: mrp: Add 'enum br_mrp_hw_support' Applying: bridge: mrp: Extend br_mrp_switchdev to detect better the errors error: patch failed: net/bridge/br_mrp_switchdev.c:177 error: net/bridge/br_mrp_switchdev.c: patch does not apply Patch failed at 0004 bridge: mrp: Extend br_mrp_switchdev to detect better the errors hint: Use 'git am --show-current-patch' to see the failed patch When you have resolved this problem, run "git am --continue". If you prefer to skip this patch, run "git am --skip" instead. To restore the original branch and stop patching, run "git am --abort".
