* avcodec/me_cmp: Remove ff_check_alignment()Andreas Rheinhardt2021-01-211-23/+0
| | | | | | | | | | | | | | | | | The usage of a static variable presents a potential for data races and means that this function can't be used in init functions of codecs with FF_CODEC_CAP_INIT_THREADSAFE (unless of course one presumes that everything is alright in which case the error is not triggered; but then the whole function is pointless...). This makes the Snow decoder init-threadsafe as it already claims. Notice that this function has been removed in 2014 by Libav in commit 9103185bd116930f90b847090e66a64fa9971ce2, because only some codepaths are checked this way and because it only affects legacy compilers. The latter is of course even more true today. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
