ALSA: rme32: Convert to generic PCM copy ops
This patch converts the rme32 driver code to use the new unified PCM copy callback. It's a straightforward conversion from *_user() to *_iter() variants. Link: https://lore.kernel.org/r/20230815190136.8987-11-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
