ALSA: move line6 usb driver into sound/usb

2015-01-12T21:29:57Z

Promote line6 driver from staging to sound/usb/line6 directory, and maintain through sound subsystem tree. This commit just moves the code and adapts Makefile / Kconfig. The further renames and misc cleanups will follow. Signed-off-by: Takashi Iwai

staging: line6: Make *_disconnect() functions static

2015-01-12T21:24:11Z

Remove declarations from the header and move the definitions up in the source so they need not be forward declared. Signed-off-by: Chris Rorvick Reviewed-by: Stefan Hajnoczi Signed-off-by: Greg Kroah-Hartman Signed-off-by: Takashi Iwai

staging: line6: Call *_disconnect() via pointer

2015-01-12T21:24:11Z

Which *_disconnect() to call on disconnect is known at initialization. Add a function pointer to the `usb_line6' struct and use to call into the appropriate logic instead of evaluating the conditional logic.

staging: line6: Call *_process_message() via pointer

2015-01-12T21:24:10Z

Which *_process_message() function (if any) to call when data is received is known at initialization. Add a function pointer to the `usb_line6' struct and use to call into the appropriate logic instead of evaluating the conditional logic for each message.

staging: line6: Pass *_process_message() `usb_line6' pointers

2015-01-12T21:24:10Z

Casting the `struct usb_line6' pointer at the call point makes the code difficult to read. This is substantially cleaned up by moving the cast into the callees. Signed-off-by: Chris Rorvick Reviewed-by: Stefan Hajnoczi Signed-off-by: Greg Kroah-Hartman Signed-off-by: Takashi Iwai

staging: line6: Move audio endpoints to properties

2015-01-12T21:24:08Z

The device type can now be used to determine the addresses of the audio endpoints for the interface. Drop the conditional logic and make these values properties. Signed-off-by: Chris Rorvick Reviewed-by: Stefan Hajnoczi Signed-off-by: Greg Kroah-Hartman Signed-off-by: Takashi Iwai
