Subject: KVM: PIT: fix i8254 pending count read
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d2a8284e8fca9e2a938bee6cd074064d23864886;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

KVM: PIT: fix i8254 pending count read

count_load_time assignment is bogus: its supposed to contain what it
means, not the expiration time.
