Subject: x86: nmi_watchdog - remove useless check
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=2b6addad2d67a2d75ae10a1c8efd18d81d78ff82;p=deliverable%2Flinux.git

x86: nmi_watchdog - remove useless check

Since nmi_watchdog is unsigned variable we may
safely remove the check for negative value.
