## Description

In the Linux kernel, the following vulnerability has been resolved:  mtd: intel-dg: Fix accessing regions before setting nregions  The regions array is counted by nregions, but it's set only after accessing it:  [] UBSAN: array-index-out-of-bounds in drivers/mtd/devices/mtd_intel_dg.c:750:15 [] index 0 is out of range for type '<unknown> [*]'  Fix it by also fixing an undesired behavior: the loop silently ignores ENOMEM and continues setting the other entries.
