From 237c0ee4742b6462cb41cdb3fda1ca55011e4aaf Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Thu, 26 May 2022 22:56:42 +0200 Subject: riscv: drop cpufeature_apply_feature tracking variable The variable was tracking which feature patches got applied but that information was never actually used - and thus resulted in a warning as well. Drop the variable.
