Subject: [PATCH 2/6] ata: sata_rcar: Fix compilation warning
Date: Mon, 17 Oct 2022 12:22:01 +0900	[thread overview]
Message-ID: <20221017032205.2210188-3-damien.lemoal@opensource.wdc.com> (raw)
In-Reply-To: <20221017032205.2210188-1-damien.lemoal@opensource.wdc.com>

When compiling with clang and W=1, the following warning is generated:

drivers/ata/sata_rcar.c:878:15: error: cast to smaller integer type
'enum sata_rcar_type' from 'const void *'
[-Werror,-Wvoid-pointer-to-enum-cast]
        priv->type = (enum sata_rcar_type)of_device_get_match_data(dev);
                     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Fix this by using a cast to unsigned long to match the "void *" type
size returned by of_device_get_match_data().
