Give each of these init and exit functions unique driver-specific names to eliminate the anonymous names. Example 1: (System.map) ffffffff832fc78c t init ffffffff832fc79e t init ffffffff832fc8f8 t init Example 2: (initcall_debug log) calling init+0x0/0x12 @ 1 initcall init+0x0/0x12 returned 0 after 15 usecs calling init+0x0/0x60 @ 1 initcall init+0x0/0x60 returned 0 after 2 usecs calling init+0x0/0x9a @ 1 initcall init+0x0/0x9a returned 0 after 74 usecs Fixes: 80fd9cd52de6 ("usbip: vudc: Add VUDC main file") Signed-off-by: Randy Dunlap Cc: Krzysztof Opasiak Cc: Igor Kotrasinski Cc: Greg Kroah-Hartman Cc: Valentina Manea Cc: Shuah Khan Cc: Shuah Khan Cc: linux-usb@vger.kernel.org Acked-by: Shuah Khan --- drivers/usb/usbip/vudc_main.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) --- lnx-517-rc8.orig/drivers/usb/usbip/vudc_main.c +++ lnx-517-rc8/drivers/usb/usbip/vudc_main.c @@ -28,7 +28,7 @@ static struct platform_driver vudc_drive static struct list_head vudc_devices = LIST_HEAD_INIT(vudc_devices); -static int __init init(void) +static int __init vudc_init(void) { int retval = -ENOMEM; int i; @@ -86,9 +86,9 @@ cleanup: out: return retval; } -module_init(init); +module_init(vudc_init); -static void __exit cleanup(void) +static void __exit vudc_cleanup(void) { struct vudc_device *udc_dev = NULL, *udc_dev2 = NULL; @@ -103,7 +103,7 @@ static void __exit cleanup(void) } platform_driver_unregister(&vudc_driver); } -module_exit(cleanup); +module_exit(vudc_cleanup); MODULE_DESCRIPTION("USB over IP Device Controller"); MODULE_AUTHOR("Krzysztof Opasiak, Karol Kosik, Igor Kotrasinski");
