[FFmpeg-devel] [PATCH 3/7] avcodec/pgxdec: Remove pointless checks

[Andreas Rheinhardt]

These checks were (most likely) added to check for overreads
as the bytestream2_get_* functions return 0 in this case.
Yet this is not necessary anymore as we now have an explicit check
for the size. Should the input contain a real \0, pgx_get_number()
will error out lateron.
