Original commit message from CVS: * gst/audiofx/audiochebband.c: (gst_audio_cheb_band_class_init), (gst_audio_cheb_band_init), (gst_audio_cheb_band_finalize), (gst_audio_cheb_band_set_property): * gst/audiofx/audiochebband.h: * gst/audiofx/audiocheblimit.c: (gst_audio_cheb_limit_class_init), (gst_audio_cheb_limit_init), (gst_audio_cheb_limit_finalize), (gst_audio_cheb_limit_set_property): * gst/audiofx/audiocheblimit.h: * gst/audiofx/audiowsincband.c: (gst_audio_wsincband_class_init), (gst_audio_wsincband_init), (gst_audio_wsincband_finalize), (gst_audio_wsincband_set_property): * gst/audiofx/audiowsincband.h: * gst/audiofx/audiowsinclimit.c: (gst_audio_wsinclimit_class_init), (gst_audio_wsinclimit_init), (gst_audio_wsinclimit_finalize), (gst_audio_wsinclimit_set_property): * gst/audiofx/audiowsinclimit.h: Use a custom mutex for protecting the instance fields instead of the GstObject lock. Using the latter can lead to deadlocks, especially with the FIR filters when updating the latency.
