Subject: [PATCH v4 6/6] PCI: rcar-gen4: fix -Wvoid-pointer-to-enum-cast warning
Date: Wed, 20 Dec 2023 14:38:29 +0900 [thread overview]
Message-ID: <20231220053829.1921187-7-yoshihiro.shimoda.uh@renesas.com> (raw)
In-Reply-To: <20231220053829.1921187-1-yoshihiro.shimoda.uh@renesas.com>
When building with clang 18 with adding -Wvoid-pointer-to-enum-cast,
the following error happens:
drivers/pci/controller/dwc/pcie-rcar-gen4.c:439:15: error: cast to smaller integer type 'enum dw_pcie_device_mode' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
439 | rcar->mode = (enum dw_pcie_device_mode)of_device_get_match_data(&rcar->pdev->dev);
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To fix this issue, use uintptr_t instead.
