Posted by marcandre.lureau@redhat.com 3 years, 9 months ago

From: Marc-André Lureau <marcandre.lureau@redhat.com>

Also fixes a GCC 12.0.1 false-positive:
../hw/arm/digic.c: In function ‘digic_init’:
../hw/arm/digic.c:45:54: error: ‘%d’ directive output may be truncated writing between 1 and 11 bytes into a region of size 5 [-Werror=format-truncation=]
   45 |         snprintf(name, DIGIC_TIMER_NAME_MLEN, "timer[%d]", i);
      |                                                      ^~
