[PATCH 5.10 337/352] Fix gcc 4.9 build issue in 5.10.y

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



5.10-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 5.10 337/352] gcc-4.9 warning/error fix for 5.10.223-rc1
Fixes: fd7eea27a3ae ("Compiler Attributes: Add __uninitialized macro")
