From 15b55dcb8ceb0b6b9c788613b3746384eff7f6fe Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 28 Jun 2013 11:51:32 +0200 Subject: [PATCH] ALSA: hda - Fix the max length of control name in generic parser add_control_with_pfx() in hda_generic.c assumes a shorter name string for the control element, and this resulted in the truncation of the long but valid string like "Headphone Surround Switch" in the middle. This patch aligns the max size to the actual limit of snd_ctl_elem_id, 44.
