[PATCH 2/2] arm64: dts: qcom: sdm850-huawei-matebook-e-2019: Correct ipa_fw_mem for the driver to load successfully

From: Jingzhou Zhu

Date: Sun Dec 07 2025 - 22:15:38 EST


The ipa driver refuses to load with the old ipa_fw_mem in newer kernels.
Shrinking its size to 0x5a000 fixes the problem.

Fixes: aab69794b55d ("arm64: dts: qcom: Add support for Huawei MateBook E 2019")
