Bhumika Goyal	2ab3c34c9c	usb: gadget: make snd_pcm_hardware const ... Make this const as it is only used during a copy operation. Done using Coccinelle. Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>	2017-08-28 11:39:33 +02:00
Arvind Yadav	640c0be81b	usb: gadget: f_uac2: constify snd_pcm_ops structures ... snd_pcm_ops are not supposed to change at runtime. All functions working with snd_pcm_ops provided by <sound/pcm.h> work with const snd_pcm_ops. So mark the non-const structs as const.

Ruslan Bilovol	eb9fecb9e6	usb: gadget: f_uac2: split out audio core ... Abstract the peripheral side ALSA sound card code from the f_uac2 function into a component that can be called by various functions, so the various flavors can be split apart and selectively reused. Visible changes: - add uac_params structure to pass audio paramteres for g_audio_setup - make ALSA sound card's name configurable - add [in/out]_ep_maxpsize - allocate snd_uac_chip structure during g_audio_setup - add u_audio_[start/stop]_[capture/playback] functions Signed-off-by: Ruslan Bilovol <ruslan.bilovol@gmail.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>	2017-06-19 09:22:46 +03:00
