Subject: [PATCH 2/2] arm64: dts: qcom: sdm850-huawei-matebook-e-2019: Correct ipa_fw_mem for the driver to load successfully
Date: Mon, 8 Dec 2025 11:15:11 +0800 [thread overview]
Message-ID: <20251208031511.3284-3-newwheatzjz@zohomail.com> (raw)
In-Reply-To: <20251208031511.3284-1-newwheatzjz@zohomail.com>
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")
