From 17074c1a5f1bbbf352fe071b2947a498db42661f Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Fri, 11 Dec 2015 15:52:37 +0100 Subject: [PATCH] ALSA: usb-audio: constify usb_protocol_ops structures The usb_protocol_ops structures are never modified, so declare them as const. Done with the help of Coccinelle.
