Revision 0d33b1baeb6ca7165d5ed4fdd1a8f969985e35b9 authored by Paolo Bonzini on 13 October 2021, 16:29:42 UTC, committed by Paolo Bonzini on 22 October 2021, 14:02:07 UTC 
KVM: x86: leave vcpu->arch.pio.count alone in emulator_pio_in_out
 
Currently emulator_pio_in clears vcpu->arch.pio.count twice if
emulator_pio_in_out performs kernel PIO.  Move the clear into
emulator_pio_out where it is actually necessary.

No functional change intended.
