[alsa-devel] [PATCH] ALSA: uapi: #include <time.h> in asound.h

[Daniel Mentz]

The uapi header asound.h defines types based on struct timespec. We need
to #include <time.h> to get access to the definition of this struct.

Previously, we encountered the following error message when building
applications with a clang/bionic toolchain:

kernel-headers/sound/asound.h:350:19: error: field has incomplete type 'struct timespec'
  struct timespec trigger_tstamp;
                  ^

The absence of the time.h #include statement does not cause build errors
with glibc, because its version of stdlib.h indirectly includes time.h.
