From e0df7e1faebad9a7ac0931d03f86fcd5c0d1896e Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Thu, 16 Apr 2015 12:44:53 -0700 Subject: checkpatch: avoid "spaces required around that ':'" false positive Since commit 1f65f947a6a8 ("checkpatch: add checks for question mark and colon spacing") back in 2008, checkpatch has reported false positive for asm volatile uses of "::" checkpatch thinks colons should always have spaces around it. Add an exception for colons with colons on either side for this valid asm volatile (and c++) use.
