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.
