From e8fbdf1855f7f31a8f37df60d7be44d8aabe6288 Mon Sep 17 00:00:00 2001 From: Damien Le Moal Date: Fri, 14 Oct 2022 10:45:58 +0900 Subject: ata: ahci_xgene: Fix compilation warning When compiling with clang and W=1, the following warning is generated: drivers/ata/ahci_xgene.c:788:14: error: cast to smaller integer type 'enum xgene_ahci_version' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast] version = (enum xgene_ahci_version) of_devid->data; ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Fix this by using a cast to unsigned long to match the "void *" type size of of_devid->data.
