From 71bdc8fe22ace3554144911a49d5d973b7e8a49f Mon Sep 17 00:00:00 2001 From: Punit Agrawal Date: Tue, 14 Sep 2021 23:39:06 +0900 Subject: [PATCH] csky: ftrace: Drop duplicate implementation of arch_check_ftrace_location() The csky specific arch_check_ftrace_location() shadows a weak implementation of the function in core code that offers the same functionality but with additional error checking. Drop the architecture specific function as a step towards further cleanup in core code.
