From 7d7b0c85127cbac45e6c4e0ae0647ace17cadfaf Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Fri, 14 Oct 2022 10:42:57 +0900 Subject: [PATCH] ata: ahci_brcm: Fix compilation warning When compiling with clang and W=1, the following warning is generated: drivers/ata/ahci_brcm.c:451:18: error: cast to smaller integer type 'enum brcm_ahci_version' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast] priv->version = (enum brcm_ahci_version)of_id->data; ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Fix this by using a cast to unsigned long to match the "void *" type size of of_id->data.
