5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jari Ruusu jariruusu@protonmail.com
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.
