[PATCH 68/71] ncr5380: Fix whitespace issues using regexp
From: Finn Thain
Date: Wed Nov 18 2015 - 03:54:42 EST
This patch is just the result of two substitutions. The first removes any
tabs and spaces at the end of the line. The second replaces runs of
tabs and spaces at the beginning of comment lines with a single space.
perl -i -pe 's,[\t ]+$,,; s,^(\t*[/ ]\*)[ \t]+,$1 ,' drivers/scsi/{atari_,}NCR5380.c
This removes some unimportant discrepancies between the two core driver
forks so that 'diff' can be used to reveal the important ones, to
facilitate reunification.
