Subject: [PATCH 5.10 046/125] memory: tegra: Fix compilation warnings on 64bit platforms

From: Dmitry Osipenko <digetx@...il.com>

[ Upstream commit e0740fb869730110b36a4afcf05ad1b9d6f5fb6d ]

Fix compilation warning on 64bit platforms caused by implicit promotion
of 32bit signed integer to a 64bit unsigned value which happens after
enabling compile-testing of the EMC drivers.
