Subject: [PATCH 0/6] remove unnecessary return val of kvm pit

From: Miaohe Lin <linmiaohe@...wei.com>

The return val of kvm pit function is always equal to 0, which means there
is no way to failed with this function. So remove the return val as it's
unnecessary to check against it. Also add BUILD_BUG_ON to guard against
channels size changed unexpectly.

Miaohe Lin (6):
  KVM: x86: remove always equal to 0 return val of
    kvm_vm_ioctl_get_pit()
  KVM: x86: remove always equal to 0 return val of
    kvm_vm_ioctl_set_pit()
  KVM: x86: remove always equal to 0 return val of
    kvm_vm_ioctl_get_pit2()
  KVM: x86: remove always equal to 0 return val of
    kvm_vm_ioctl_set_pit2()
  KVM: x86: check kvm_pit outside kvm_vm_ioctl_reinject()
  KVM: x86: remove always equal to 0 return val of
    kvm_vm_ioctl_reinject()
