From 919ed52f33a9250b5707804b1a84b4b7cbfe2333 Mon Sep 17 00:00:00 2001 From: Akshay Joshi Date: Tue, 7 Jun 2011 04:51:55 -0400 Subject: [PATCH] Staging: Winbond: Fix assorted spacing issues. Fix the phy_calibration.c file's spacing issues and convert the spaces to tabs. This reduces the number of errors and warnings returned by checkpatch.pl.
