[vlc-devel] [PATCH] decoder: remove misleading comment

[Steve Lhomme]

The p_aout and p_vout need locking for reading as well (it wouldn't make much
sense to only lock when writing).

For example p_aout can be modified in the DecoderThread during a ReloadDecoder.

p_vout cannot be modified outside of the vout_update_format/spu_new_buffer but
it is also access in the DecoderThread, for example during DecoderProcessFlush()
or the OutputChangeXXX functions.

For functions only called by the decoder, it might be OK not to lock as the
p_out/p_aout should only change during vout_update_format/aout_update_format
which the decoder should call before doing other calls from various threads.
