From 6f62b58dd4e697a23a308f5b77781394949d333e Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Tue, 8 Dec 2009 16:29:37 -0700 Subject: [PATCH] OMAP1 clock: convert test in disable_unused() to use ENABLE_ON_INIT mach-omap1/clock.c:omap1_clk_disable_unused() contains a test that assumes that the clock structures are available in the file's namespace. After a following patch, this will no longer be the case. So we need to reimplement that test. It turns out that we already have a facility in the clock framework to handle this case - the ENABLE_ON_INIT flag - used on OMAP2/3. Remove the offending test and mark the clocks that it was intended to catch as ENABLE_ON_INIT.
