From af3948929b10ec39f185192c25fc81d8c61714bf Mon Sep 17 00:00:00 2001 From: Jari Ruusu Date: Fri, 26 Jul 2024 09:53:18 +0000 Subject: [PATCH] Fix gcc 4.9 build issue in 5.4.y Some older systems still compile kernels with old gcc version. These warnings and errors show up when compiling with gcc 4.9.2 error: "__GCC4_has_attribute___uninitialized__" is not defined [-Werror=undef] Upstream won't need this because newer kernels are not compilable with gcc 4.9.
