Subject: [PATCH v2 2/6] thread.h: Fix Coverity version of qemu_cond_timedwait()
Date: Thu, 19 Mar 2020 19:33:19 +0000	[thread overview]
Message-ID: <20200319193323.2038-3-peter.maydell@linaro.org> (raw)
In-Reply-To: <20200319193323.2038-1-peter.maydell@linaro.org>

For Coverity's benefit, we provide simpler versions of functions like
qemu_mutex_lock(), qemu_cond_wait() and qemu_cond_timedwait().  When
we added qemu_cond_timedwait() in commit 3dcc9c6ec4ea, a cut and
paste error meant that the Coverity version of qemu_cond_timedwait()
was using the wrong _impl function, which makes the Coverity parser
complain:

"/qemu/include/qemu/thread.h", line 159: warning #140: too many arguments in
          function call
      return qemu_cond_timedwait(cond, mutex, ms);
             ^

"/qemu/include/qemu/thread.h", line 159: warning #120: return value type does
          not match the function type
      return qemu_cond_timedwait(cond, mutex, ms);
             ^

"/qemu/include/qemu/thread.h", line 156: warning #1563: function
          "qemu_cond_timedwait" not emitted, consider modeling it or review
          parse diagnostics to improve fidelity
  static inline bool (qemu_cond_timedwait)(QemuCond *cond, QemuMutex *mutex,
                      ^

These aren't fatal, but reduce the scope of the analysis. Fix the error.
