ALSA: opti9xx: Allocate resources with device-managed APIs
This patch converts the resource management in ISA als100 driver with devres as a clean up. Each manual resource management is converted with the corresponding devres helper. This should give no user-visible functional changes. Link: https://lore.kernel.org/r/20210715075941.23332-68-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
