[FFmpeg-devel] [PATCH] avutil/frame: move wipe_side_data counter to its utilized scope

[Andreas Rheinhardt]

Jan Ekström:
> Originally in 77b2cd7b41d7ec8008b6fac753c04f77824c514c this
> counter was separate in av_frame_unref, in which the same counter
> was re-utilized multiple times over multiple loops.
> 
> This code was then refactored into wipe_side_data as-is in
> 5d839778b9f3edb682b7f71dde4f80f07c75b098 , keeping the location of
> counter initialization. This was unnecessary, as the counter was
> no longer utilized outside of the for loop's scope and thus could
> reside within the loop itself.

Don't create a patch for a single for loop; do this for all for loops in
this file where it is possible.
