5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jari Ruusu <jariruusu@xxxxxxxxxxxxxx>
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.
Subject: [PATCH 5.4 249/259] gcc-4.9 warning/error fix for 5.10.223-rc1
Fixes: fd7eea27a3ae ("Compiler Attributes: Add __uninitialized macro")
