From e715bc42e337b6f54ada7262e1bbc0b7860525c2 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Fri, 19 Dec 2025 18:16:15 +0100 Subject: usb: gadget: Constify struct configfs_item_operations and configfs_group_operations 'struct configfs_item_operations' and 'configfs_group_operations' are not modified in these drivers. Constifying these structures moves some data to a read-only section, so increases overall security, especially when the structure holds some function pointers. On a x86_64, with allmodconfig, as an example: Before: ====== text data bss dec hex filename 65061 20968 256 86285 1510d drivers/usb/gadget/configfs.o After: ===== text data bss dec hex filename 66181 19848 256 86285 1510d drivers/usb/gadget/configfs.o Signed-off-by: Christophe JAILLET Link: https://patch.msgid.link/49cec1cb84425f854de80b6d69b53a5a3cda8189.1766164523.git.christophe.jaillet@wanadoo.fr Signed-off-by: Greg Kroah-Hartman --- drivers/usb/gadget/function/f_serial.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'drivers/usb/gadget/function/f_serial.c') diff --git a/drivers/usb/gadget/function/f_serial.c b/drivers/usb/gadget/function/f_serial.c index 0f266bc067f5..e6b412e0e045 100644 --- a/drivers/usb/gadget/function/f_serial.c +++ b/drivers/usb/gadget/function/f_serial.c @@ -260,7 +260,7 @@ static void serial_attr_release(struct config_item *item) usb_put_function_instance(&opts->func_inst); } -static struct configfs_item_operations serial_item_ops = { +static const struct configfs_item_operations serial_item_ops = { .release = serial_attr_release, }; -- cgit v1.2.3
