From 33c42bb88c99ccd5d028236b5dc022cd1a542f3a Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Fri, 17 Jul 2015 02:21:47 +0200 Subject: ddr: altera: Internal mem_calibrate() cleanup part 1 This is kind of microseries-within-series indent cleanup. Rework the code for the first loop within the middle-loop of the mega-loop to make it actually readable and not an insane cryptic pile of indent failure. It is likely that this patch has checkpatch warnings, but for the sake of not breaking the code, these are ignored. No functional change.
