Subject: [PATCH 02/15] hw/arm/boot: fix uninitialized scalar variable warning
391fb8
 reported by coverity
391fb8
391fb8
Coverity reports the 'size' may be used uninitialized, but that can't happen,
391fb8
because the caller has checked "if (binfo->dtb_filename || binfo->get_dtb)"
391fb8
before call 'load_dtb'.
391fb8
391fb8
Here we simply remove the 'if (binfo->get_dtb)' to satisfy coverity.
