[Qemu-devel] [PATCH v2 6/6] audio: Fix using freed pointer in wav_fini_o

Subject: [Qemu-devel] [PATCH v2 6/6] audio: Fix using freed pointer in wav_fini_out()
Date: Wed, 28 May 2014 21:21:40 +0800

From: Gonglei <address@hidden>

Spotted by Coverity:

(8) Event freed_arg:  "fclose(FILE *)" frees "wav->f".
(9) Event cond_true:  Condition "fclose(wav->f)", taking true branch
Also see events:  [pass_freed_arg]

212         if (fclose (wav->f))  {
(10) Event pass_freed_arg:  Passing freed pointer "wav->f" as an argument
to function "AUD_log(char const *, char const *, ...)".
Also see events:  [freed_arg]

213             dolog ("wav_fini_out: fclose %p failed\nReason: %s\n",
214                    wav->f, strerror (errno));

Removed wav->f's pointer in error log, actually it's uselessly.
