From c312cef223ddc164b8d3fd3a195eb88a43ede901 Mon Sep 17 00:00:00 2001 From: Sergey Sergeev Date: Thu, 30 Jun 2016 13:23:15 +0300 Subject: [PATCH] ar71xx: spi-rb4xx fix. In new kernels we should use clk_prepare_enable instead of clk_enable since clk_enable does not make proper initialization that leads to rise WARN_ON messages and not working spi bus on the device.
