Subject: KVM: s390: fix sigp sense running condition code handling
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7ba26c482fcb42b01785ee1f39871fcc636ab3fe;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

KVM: s390: fix sigp sense running condition code handling

Only if the sensed cpu is not running a status is stored, which
is reflected by condition code 1. If the cpu is running, condition
code 0 should be returned.
Just the opposite of what the code is doing.
