Subject: usb: dwc3: gadget: pass a condition to dev_WARN_ONCE()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=95ca961c758cd9ce789247098b09c39017637e58;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

usb: dwc3: gadget: pass a condition to dev_WARN_ONCE()

instead of using:

	if (condition) {
		dev_WARN_ONCE(dev, true, "foo");
		return -EINVAL;
	}

let's use:

	if (dev_WARN_ONCE(dev, condition, "foo"))
		return -EINVAL;
