From f72896721621689460967301a54a3d380d0e9434 Mon Sep 17 00:00:00 2001 From: Justin Stitt Date: Wed, 20 Dec 2023 14:38:28 +0900 Subject: PCI: iproc: Fix -Wvoid-pointer-to-enum-cast warning MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When building with clang 18, the following warning will be reported: drivers/pci/controller/pcie-iproc-platform.c:54:15: warning: cast to smaller integer type 'enum iproc_pcie_type' from 'const void *' [-Wvoid-pointer-to-enum-cast] 55 | pcie->type = (enum iproc_pcie_type) of_device_get_match_data(dev); To fix this issue, cast the data the of_device_get_match_data() helper returns to uintptr_t rather than the iproc_pcie_type enum.
