Subject: kgdb,x86: remove redundant test
X-Git-Tag: upstream/snapshot3+hdmi~16378^2~8
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a5d09d68335bb8422d5e7050c9f03f99ba6cfebd;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

kgdb,x86: remove redundant test

The for loop starts with a breakno of 0, and ends when it's 4. so
this test is always true.
