[PATCH] soc: qcom: mdt_loader: Fix split-firmware condition

From: Bjorn Andersson
Date: Mon Feb 14 2022 - 22:46:13 EST


The updated condition checking if a segment can be found in the loaded
firmware blob, or need to be loaded from a separate file, incorrectly
classifies segments that ends at the end of the loaded blob. The result
is that the mdt loader attempts to load the segment from a separate
file.

Correct the conditional to use the loaded segment instead.
