I never managed to reproduce this warning. Any idea what is going on here, or which patch fixed it in newer kernels?

does not seem to be fixed, in next-20170125
make allyesconfig make drivers/isdn/hardware/eicon/message.o CC drivers/isdn/hardware/eicon/message.o In file included from drivers/isdn/hardware/eicon/message.c:30:0: drivers/isdn/hardware/eicon/message.c: In function 'mixer_notify_update': drivers/isdn/hardware/eicon/platform.h:333:18: warning: array subscript is above array bounds [-Warray-bounds] *(__le16 *)addr = cpu_to_le16(v);
will issue the above warning
thx! hofrat

Very odd. http://arm-soc.lixom.net/buildlogs/next/next-20170125/ does not show it, so something must have changed for Olof but not for you:

will issue the above warning
which CPU architecture and compiler version is this?
I have tried various aarch64 and x86_64 toolchains and could finally reproduce it on x86_64-linux-gcc-4.9, but no other version (Olof's build bot found it on aarch64). I'll try to come up with a patch that fixes this case.
Thanks!

sorry that was a bit braindead on my side x86_64 gcc (Debian 4.9.2-10) 4.9.2
