[Devel] [PATCH vz10 14/15] selftests/uevent: fix -Wmaybe-uninitialized warning in uevent_filtering

[Konstantin Khorenko]

  uevent_filtering.c: In function 'trigger_uevent':
  uevent_filtering.c:217:16: warning: 'ret' may be used uninitialized [-Wmaybe-uninitialized]
    217 |         return ret;
        |                ^~~
  uevent_filtering.c:197:17: note: 'ret' was declared here
    197 |         int fd, ret;
        |                 ^~~

Initialize 'ret' to 0 in trigger_uevent(). If 'times' is 0, the for
loop body is never entered and 'ret' would be returned uninitialized.
