This patch converts the resource management in PCI emu10k1 driver with devres as a clean up. Each manual resource management is converted with the corresponding devres helper, the page allocations are done with the devres helper, and the card object release is managed now via card->private_free instead of a lowlevel snd_device. This should give no user-visible functional changes. Link: https://lore.kernel.org/r/20210715075941.23332-34-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
