Subject: usb: dwc3: gadget: Fix usage of bitwise operator
X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=d07fa665c79d85fead080f4b611c3f7645576454;p=deliverable%2Flinux.git

usb: dwc3: gadget: Fix usage of bitwise operator

Cleans up the sparse warning:
warning: dubious: x | !y

Since we do want a bitwise OR here, don't use a logical (true/false)
value. Probably is not a real issue but it cleans up the warning.
