From dbb674d57b5851a4fe3122ff4280e4cf87209198 Mon Sep 17 00:00:00 2001 From: Russell King Date: Thu, 22 Jan 2009 16:08:04 +0000 Subject: [PATCH] [ARM] omap: allow double-registering of clocks This stops things blowing up if a 'struct clk' to be passed more than once to clk_register(), which will be required when we decouple struct clk's from their names.
