Subject: vmbus: drop no longer used kick_q argument
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b103a56f80878b4370522ec26017fcadd526f5ad;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

vmbus: drop no longer used kick_q argument

The flag to cause notification of host is unused after
commit a01a291a282f7c2e ("Drivers: hv: vmbus: Base host signaling
strictly on the ring state"). Therefore remove it from the ring
buffer internal API.
