Re: [PATCH 01/36] ALSA: rawmidi: Pass rawmidi directly to snd_rawmidi_kernel_open()

snd_rawmidi_kernel_open() is used only internally from ALSA sequencer, so far, and parsing the card / device matching table at each open is redundant, as each sequencer client already gets the rawmidi object beforehand.

This patch optimizes the path by passing the rawmidi object directly at snd_rawmidi_kernel_open(). This is also a preparation for the upcoming UMP rawmidi I/O support.
