From 17385a386ccae1b5a9a135c43493652b4dd82f61 Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Sun, 11 Oct 2015 12:30:14 +0900 Subject: [PATCH 40/50] ALSA: firewire-digi00x: use in-kernel representation for the type of 8 bits Original code for 'DoubleOhThree' encoding was written with '__u8' type, while the type is usually used to export something to userspace. This commit replaces the type with 'u8'.
