Subject: wmavoice: initialize best_hist_ptr to NULL to prevent (incorrect) warning.
X-Git-Tag: android-x86-4.4-r1~9409
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=d5fd610dabb4c7a6f63d4479e66c93c37339b6c0;p=android-x86%2Fexternal-ffmpeg.git

wmavoice: initialize best_hist_ptr to NULL to prevent (incorrect) warning.

As a sideeffect this makes the code more robust if a future change leaves
a path where it may be uninitialized otherwise.
