Thanks for the information. I am not seeing this issue or even a warning when using the ARM 8.3 toolchain even in a clean build. arm-linux-gnueabihf-gcc (GNU Toolchain for the A-profile Architecture 8.3-2019.03 (arm-rel-8.36)) 8.3.0 So is a bug in this toolchain? > This is not architecture specific but language specific thing. > > If you enter this error message got Google you will get an answer > to why this happens in the first result. I did Google the issue and got the answer I guess I just question to why I am not seeing the error because for me the patchset builds fine no errors. And why is this only reported on the MIPS arch.  Not saying that it is not an issue in the code just wondering how it gets there. > > You need to patch your driver with the attached one. > I will try to reproduce the error and then apply the changes.
