Signed-off-by: Eric Auger Reviewed-by: Arnd Bergmann --- v4 -> v5: - add Arnd's R-b v3 -> v4: - pass reset to vfio_platform_unregister_reset v2 -> v3: - use vfio_platform_register_reset macro v1 -> v2: - remove vfio_platform_reset_private.h and move back the macro to vfio_platform_private.h header: removed reset_module_register & unregister (symbol_get) - defines the module_vfio_reset_handler macro as suggested by Arnd (formerly in vfio_platform_reset_private.h) --- drivers/vfio/platform/vfio_platform_private.h | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/drivers/vfio/platform/vfio_platform_private.h b/drivers/vfio/platform/vfio_platform_private.h index c563940..fd262be 100644 --- a/drivers/vfio/platform/vfio_platform_private.h +++ b/drivers/vfio/platform/vfio_platform_private.h @@ -110,4 +110,18 @@ static struct vfio_platform_reset_node __reset ## _node = { \ }; \ __vfio_platform_register_reset(&__reset ## _node) +#define module_vfio_reset_handler(compat, reset) \ +MODULE_ALIAS("vfio-reset:" compat); \ +static int __init reset ## _module_init(void) \ +{ \ + vfio_platform_register_reset(compat, reset); \ + return 0; \ +}; \ +static void __exit reset ## _module_exit(void) \ +{ \ + vfio_platform_unregister_reset(compat, reset); \ +}; \ +module_init(reset ## _module_init); \ +module_exit(reset ## _module_exit) + #endif /* VFIO_PLATFORM_PRIVATE_H */ -- 1.9.1
