From 8defea0e957371c7c483bfe645e3105bc3d31cca Mon Sep 17 00:00:00 2001 From: "Fabio M. De Francesco" Date: Fri, 24 Sep 2021 14:26:52 +0200 Subject: staging: r8188eu: remove test in usbctrl_vendorreq() Remove unnecessary test for "!io_buf" in usbctrl_vendorreq(). This test is not necessary because io_buf has been assigned with the address of a region of dynamically allocated memory (dvobj->usb_alloc_vendor_req_buf) by rtw_init_intf_priv() in os_dep/usb_intf.c.
