Woops!  I admit I just copied the description and the patch from the PR.
How inattentive I could be while doing that?

Gerald, should the patch have actually introduced SNDCTL_DSP_HALT as the
description says?

>>  #define SNDCTL_SEQ_SYNC		_IO  ('Q', 1)
>>  #define SNDCTL_SYNTH_INFO	_IOWR('Q', 2, struct synth_info)
>>  #define SNDCTL_SEQ_CTRLRATE	_IOWR('Q', 3, int) /* Set/get timer res.(hz) */
