Here is the complete changelog for v4: Changelog: - v4: Fixed struct device pointer access (pcie->dev) for dev_err(). Verified build and passed Sashiko review checks. [Subject: PCI: mediatek: Fix integer truncation and handle oversized resources] - v3: Replaced clamping logic with strict size validation (size_order > 31 returns -EINVAL), added !size check, and updated size calculation to fls64(size - 1) to handle power-of-two sizes correctly. [Subject: PCI: mediatek: Fix integer truncation and handle oversized resources] - v2: Added size clamping for size_order > 31 to prevent overflowing the 5-bit AHB2PCIE_SIZE() macro mask. [Subject: PCI: mediatek: Fix integer truncation in fls() and clamp size] - v1: Initial submission using fls64() to handle 64-bit resource sizes and prevent integer truncation. [Subject: PCI: mediatek: Fix integer truncation in fls() for resource size] Best regards, Sreeraj
