From 1e0f8f68f764b93e8d2d0e87e23532f2186a23a1 Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Fri, 14 Apr 2017 13:13:50 +0900 Subject: ALSA: usb-line6: constify snd_kcontrol_new strucutre array In kernel APIs of ALSA control interface, drivers can create a control element set by a call of snd_ctl_new1() with a template. This template is known to have const qualifier in general cases. This commit adds the qualifier to template array, for safer program and runtime. Application of this change moves the symbol from .data section to .rodata section.
