Subject: usb: gadget: omap_udc: kfree(NULL) is safe
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=23673d7d26d81bd17cde3ed74c57b3f39585325f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

usb: gadget: omap_udc: kfree(NULL) is safe

we don't need to check for _req because
kfree(NULL) is safe. Also, if someone
actually passes a NULL pointer to be freed
by usb_ep_free_request(), he deserves any
issue he faces.
