From d25ff26840bd0af3283d8e478669abc104bb873a Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 3 Jan 2020 09:16:44 +0100 Subject: ALSA: info: Make snd_info_entry_ops as const The reference to snd_info_entry_ops is rather read-only, so declare it as a const pointer. This allows a bit more optimization. There should be no functional changes by this patch.
