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. Signed-off-by:

A few calls to snd_usb_ctl_msg wrap the function in a retry loop. In the worst case, the timeout for snd_usb_ctl_msg is 5 seconds, which when retried 10 times (for example, if a device is removed) could cause a probe to hang for ~50 seconds. Example stack trace from 3.14 which triggered a hung task timeout: Call Trace: [<ffffffffa2c1f720>] ? inet6_set_link_af.part.35+0x12/0x12 [<ffffffffa2c20309>] schedule+0x6e/0x70 [<ffffffffa2c1f81c>] schedule_timeout+0xfc/0x13c [<ffffffffa2667bbc>] ? rcu_read_unlock_sched_notrace+0x17/0x17 [<ffffffffa2c20d68>] __wait_for_common+0x153/0x190 [<ffffffffa2c20d68>] ? __wait_for_common+0x153/0x190 [<ffffffffa26890e5>] ? wake_up_state+0x12/0x12 [<ffffffffa2c20e0e>] wait_for_completion_timeout+0x1d/0x1f [<ffffffffa2a07c70>] usb_start_wait_urb+0x93/0xf1 [<ffffffffa2a07daf>] usb_control_msg+0xe1/0x11d [<ffffffffc02cd254>] snd_usb_ctl_msg+0x9c/0xf1 [snd_usb_audio] [<ffffffffc02ce191>] snd_usb_mixer_set_ctl_value+0x124/0xab1 [snd_usb_audio] [<ffffffffc02ce230>] snd_usb_mixer_set_ctl_value+0x1c3/0xab1 [snd_usb_audio] [<ffffffffc02ce58e>] snd_usb_mixer_set_ctl_value+0x521/0xab1 [snd_usb_audio] [<ffffffffc02cee88>] snd_usb_mixer_add_control+0x36a/0x1264 [snd_usb_audio] [<ffffffffc02cf323>] snd_usb_mixer_add_control+0x805/0x1264 [snd_usb_audio] [<ffffffffa2a06e11>] ? usb_free_urb+0x1a/0x1c [<ffffffffc02cfcf7>] snd_usb_mixer_add_control+0x11d9/0x1264 [snd_usb_audio] [<ffffffffc02d000f>] snd_usb_create_mixer+0xbc/0x286 [snd_usb_audio] [<ffffffffc02cac18>] 0xffffffffc02cac17 [<ffffffffa2a0aaf1>] usb_probe_interface+0x17c/0x21c [<ffffffffa29a65bc>] driver_probe_device+0xae/0x1fa [<ffffffffa29a6767>] __device_attach_driver+0x5f/0x66 [<ffffffffa29a6708>] ? driver_probe_device+0x1fa/0x1fa [<ffffffffa29a4a60>] bus_for_each_drv+0x87/0xaa [<ffffffffa29a688a>] __device_attach+0x9d/0x101 [<ffffffffa29a6913>] device_initial_probe+0x13/0x15 [<ffffffffa29a5ae6>] bus_probe_device+0x33/0x96 [<ffffffffa29a3d19>] device_add+0x328/0x547 [<ffffffffa2a09355>] usb_set_configuration+0x624/0x674 [<ffffffffa2a11949>] generic_probe+0x45/0x77 [<ffffffffa2a0a962>] usb_probe_device+0x2d/0x40 [<ffffffffa29a65bc>] driver_probe_device+0xae/0x1fa [<ffffffffa29a6767>] __device_attach_driver+0x5f/0x66 [<ffffffffa29a6708>] ? driver_probe_device+0x1fa/0x1fa [<ffffffffa29a4a60>] bus_for_each_drv+0x87/0xaa [<ffffffffa29a688a>] __device_attach+0x9d/0x101 [<ffffffffa29a6913>] device_initial_probe+0x13/0x15 [<ffffffffa29a5ae6>] bus_probe_device+0x33/0x96 [<ffffffffa29a3d19>] device_add+0x328/0x547 [<ffffffffa29030bc>] ? add_device_randomness+0x111/0x130 [<ffffffffa2a00967>] usb_new_device+0x2a2/0x3c0 [<ffffffffa2a02ddc>] hub_thread+0xa3d/0xeed [<ffffffffa2c2010d>] ? __schedule+0x41e/0x5ac [<ffffffffa26957ce>] ? finish_wait+0x62/0x62 [<ffffffffa2a0239f>] ? usb_reset_device+0x16a/0x16a [<ffffffffa267b255>] kthread+0x108/0x110 [<ffffffffa267b14d>] ? __kthread_parkme+0x67/0x67 [<ffffffffa2c23b2c>] ret_from_fork+0x7c/0xb0 [<ffffffffa267b14d>] ? __kthread_parkme+0x67/0x67 Signed-off-by:
