From: Paulo Zanoni Date: Mon, 5 Aug 2013 20:25:55 +0000 (-0300) Subject: drm/i915: silence useless messages about DDI buffer translation X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f72d19f069f8efaa535aacc719d23d469b0d9f18;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git drm/i915: silence useless messages about DDI buffer translation These messages are not really useful since it's very easy to check which mode is used for each port: The values programmed are based on the port type, then assigned to the ddi_translations variable. Currently we use DP mode for ports A-D and FDI mode for port E. Also, when we add the code to enable/disable PC8+, intel_prepare_ddi_buffers will be called more often and will eat your dmesg buffers. While at it, fix the coding style of the "for" statement above.
