>From 20397009e13e6111c8b17e5cbaf0addf3aaf593a Mon Sep 17 00:00:00 2001 From: Sam Ravnborg <srn@xxxxxxx> Date: Mon, 3 Jul 2017 21:21:02 +0200 Subject: [PATCH 1/3] clk: fix clk_get error handling MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit If there is no OFTREE support of_clk_get_by_name failed with -ENOENT, which caused clk_get to bail out. This had the effect that nothing was printed on the serial console with at91sam9263-ek. There are no error paths that will return -ENODEV as we test for today, so change this to -ENOENT which is in use. This allows us to contine with clk_get_sys() in case of other errors as was the intention of the original fix.
