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.
