From cbfa5184cc5f58627f08c7fad225424f565b439d Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Fri, 17 Sep 2010 12:30:11 +0200 Subject: [PATCH 1/7] ASoC: fix clkdev API usage in sh/migor.c The clkdev API doesn't use .name and .id members of struct clk for clock lookup. Instead clocks should be added to a lookup list. Without this patch audio om the Migo-R board fails silently.
