From 2abb80176cd80ad8e939ead9c785ac17dc9890a4 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 8 May 2012 17:27:03 +0200 Subject: [PATCH] sound: allow the unit search until 256 in sound_core.c The upper limit of the available minors isn't necessarily 128 + unit, but it's rather up to 256. Fixing this allows more than 8 devices.
