[PATCH 0/2] Add QEMU_WARN_UNUSED_RESULT function attribute

[Manos Pitsidianakis]

Functions that return a value to indicate success or failure can be 
decorated with the warn_unused_result attribute. GCC will stop 
compilation if a caller does not check the return value after calling 
such a function. This was not possible to spot statically before, but 
Coverity detects this kind of bug. I was prompted by

CAFEAcA_TS-B0gc-DUYT6BaKnm8Uauhsx3rW2dmVNUgTToVjSJg@mail.gmail.com/">https://lore.kernel.org/qemu-devel/CAFEAcA_TS-B0gc-DUYT6BaKnm8Uauhsx3rW2dmVNUgTToVjSJg@mail.gmail.com/

to prevent this from happening in the future.
