* ALSA: emu10k1x: Allocate resources with device-managed APIsTakashi Iwai2021-07-191-98/+30
| | | | | | | | | | | | | This patch converts the resource management in PCI emu10k1x 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/20210715075941.23332-35-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>

| | | | | | | | | | | | | | | | | Recently we updated the content in alsa-lib uapi header files by just copying from the latest Linus kernel uapi/*.h, and noticed that it broke the build of some alsa-tools programs. The reason is that we used to have a modified version in the past, so that the program can be built without referring to the unexported stuff like snd_ctl_elem_id or __user prefix. This patch attempts to restore that, i.e. dropping the stuff that can't be referred in the user-space. For adapting the changes in uapi/emu10k1.h, the emu10k1 driver code is also slightly modified. Most of changes are pointer cast. Link: https://lore.kernel.org/r/20191220153415.2740-2-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
