Without the header being explicitly included, scan-build run on CI was returning errors for these files, such as: include the header <stdlib.h> or explicitly provide a declaration for 'calloc' The functions in question were calloc, free, etc. Change-Id: I4b79c5f86c074c456533296c309293e4064abe3f Signed-off-by: Anastasia Klimchuk <aklm@flashrom.org> Reviewed-on: https://review.coreboot.org/c/flashrom/+/84455 Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
