From b9452ea09f8756b2d43e527e86213bedf6007597 Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Tue, 21 Jul 2015 05:54:39 +0200 Subject: [PATCH] ddr: altera: Clean up rw_mgr_mem_calibrate_write_test() part 2 Clean up coding style, mostly broken multiline formatting strings in debug output. Also clean up data types and constify where applicable.
