From 6f81ba19ace2282f2560f5ec3a827ec5370825cb Mon Sep 17 00:00:00 2001 From: Takashi Sakamoto Date: Thu, 1 Oct 2015 22:02:12 +0900 Subject: [PATCH 26/32] ALSA: firewire-tascam: add a structure for model-dependent parameters. TASCAM FireWire series doesn't tell drivers their capabilities, thus the drivers should have model-dependent parameters and apply it to detected devices. This commit adds a structure to represent such parameters.
