From 32d5dc9520f0c6f60f691dd478741c774e292406 Mon Sep 17 00:00:00 2001 From: Bob Liu Date: Sat, 23 Oct 2010 05:11:58 -0500 Subject: [PATCH] USB: musb: pm: don't rely fully on clock support Since clock support is optional across processors, don't make the whole musb pm paths depend upon it. Just conditionalize the clock accesses.
