USB:gadget:designware Device controller bugfixes
This patch fixes a few bugs in USB device controller driver. The fixes are as follows 1. Adding error condition checks eg. NULL return 2. Endpoint other than endpoint 0 (control endpoint) are initialized only if usb state machine reaches STATE_ADDRESSED or above 3. Zero length packet handling corrected 4. Dead code removed 5. Bulk out endpoint returns after servicing 1 interrupt and returns back to service if more interrupts are pending Signed-off-by: Vipin Kumar <vipin.kumar@st.com> Signed-off-by: Amit Virdi <amit.virdi@st.com> Acked-by: Marek Vasut <marex@denx.de>
