[PATCH v3] Fix build with 64 bits time_t

[PATCH v3] Fix build with 64 bits time_t

[Fabrice Fontaine]

time element is deprecated on new input_event structure in kernel's
input.h [1]

This will avoid the following build failure:

hw/input/virtio-input-host.c: In function 'virtio_input_host_handle_status':
hw/input/virtio-input-host.c:198:28: error: 'struct input_event' has no member named 'time'
  198 |     if (gettimeofday(&evdev.time, NULL)) {
      |                            ^

Changes v2 -> v3 (after review of Gerd Hoffmann):
 - Replace include on <linux/input.h> by
   "standard-headers/linux/input.h" to try to fix build on rhel-7

Changes v1 -> v2 (after review of Michael S. Tsirkin):
 - Drop define of input_event_{sec,usec} as it is already done in
   include/standard-headers/linux/input.h

Now it complains about ioctl() not being declared.

/me suggests to create a fork @ gitlab.com and push your branch there,
that'll run it through CI and we have a centos7 build job there which
should catch this ...

take care,
  Gerd

I fixed the issue by including sys/ioctl.h.
However, I have a test failure due to a timeout on
check-system-centos:
https://gitlab.com/ffontaine/qemu/-/jobs/877810804
It does seem to be related to my patch. Should I send a v4 on the mailing list?

They timeout now and then, try re-run it.

Yes, please.
