This fixes the false positive
CC zipl/src/misc.o
misc.c: In function ‘misc_temp_dev’:
misc.c:313:27: warning: ‘%04d’ directive writing between 4 and 11 bytes into a region of size 5 [-Wformat-overflow=]
sprintf(filename, "zipl%04d", retry);
^~~~
misc.c:313:22: note: directive argument in the range [-2147483648, 999]
sprintf(filename, "zipl%04d", retry);
^~~~~~~~~~
misc.c:313:4: note: ‘sprintf’ output between 9 and 16 bytes into a destination of size 9
sprintf(filename, "zipl%04d", retry);
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
While at it, add an assertion that protects against a format-overflow,
e.g. if TEMP_DEV_MAX_RETRIES changes.
