krzk · damien-lemoal · commit 97e01439e902 · 2026-01-08T17:43:04.000+09:00
"version" is an enum, thus cast of pointer on 64-bit compile test with
clang W=1 causes:

  ahci_xgene.c:776:13: error: cast to smaller integer type 'enum xgene_ahci_version' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
