Subject: Drivers: hv: balloon: Initialize last_post_time on startup
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c548f3957efa57b6f1a1f4c90013232f6f488682;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Drivers: hv: balloon: Initialize last_post_time on startup

When left uninitialized, this sometimes fails the following check in
post_status():

	if (!time_after(now, (last_post_time + HZ))) {
		return;
        }

This causes unnecessary delays in reporting memory pressure to host after
booting up.
