Subject: [PATCH v3 5/6] PCI: iproc: fix -Wvoid-pointer-to-enum-cast warning
Date: Fri, 15 Dec 2023 11:29:54 +0900	[thread overview]
Message-ID: <20231215022955.3574063-6-yoshihiro.shimoda.uh@renesas.com> (raw)
In-Reply-To: <20231215022955.3574063-1-yoshihiro.shimoda.uh@renesas.com>

From: Justin Stitt <justinstitt@google.com>

When building with clang 18 I see the following warning:
|       drivers/pci/controller/pcie-iproc-platform.c:55:15: 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, use uintptr_t instead.
