+Subject: [PATCH] util/mtp-hotplug.c: Enable stack memory protection
+
+Use "return 0" instead of "exit(0)" at the end of main()
+function to enable checking for Stack Overflow at Runtime.
+
+Use "return 0" to let the program exit normally by returning from
+the main function. This allows the compiler to perform necessary
+cleanup operations, including stack canary checks.
+
+__stack_chk_fail function isn't being invoked when using exit(0) at
+the end of the main function
+$ objdump -T ./util/.libs/mtp-hotplug | grep __stack_chk_fail
+This return empty.
