When compiling with clang and W=1, the following warning is generated: drivers/ata/ahci_imx.c:1070:18: error: cast to smaller integer type 'enum ahci_imx_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast] imxpriv->type = (enum ahci_imx_type)of_id->data; ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Fix this by using a cast to unsigned long to match the "void *" type size of of_id->data.
