      Convert a 0 error return code to a negative one, as returned elsewhere in the
      function.
      
      A simplified version of the semantic match that finds this problem is as
      follows: (http://coccinelle.lip6.fr/)
      
      // <smpl>

      usb: gadget: s3c-hsotg: fix core reset timeout failure · 2868fea2
      Du, Changbin authored
      The timeout values were 1000 and timeout issue occured many times on my
      s3c6410 Soc based board (mostly when booting whith USB cable not
      connected). This patch increase the values to 10000 to guarantee the
      success of reset.
      
      Having set timeout to 10000, I printed the remained timeout values
      which could cause timeout issue before this change (tested several
      times).
      the first timeout value remained:
      	timeout = 8079
      	timeout = 8079
      	timeout = 8078
      	timeout = 8081
      the second timeout value remained:
      	timeout = 7940
      	timeout = 7945
      	timeout = 7940
      	timeout = 7938
      Seeing from above values, I think the value 10000 is big enough.

      usb: Provide usb_speed_string() function · e538dfda
      Michal Nazarewicz authored
      In a few places in the kernel, the code prints
      a human-readable USB device speed (eg. "high speed").
      This involves a switch statement sometimes wrapped
      around in ({ ... }) block leading to code repetition.
      
      To mitigate this issue, this commit introduces
      usb_speed_string() function, which returns
      a human-readable name of provided speed.
      
      It also changes a few places switch was used to use
      this new function.  This changes a bit the way the
      speed is printed in few instances at the same time
      standardising it.

      USB: use usb_endpoint_maxp() instead of le16_to_cpu() · 29cc8897
      Kuninori Morimoto authored
      Now ${LINUX}/drivers/usb/* can use usb_endpoint_maxp(desc) to get maximum packet size
      instead of le16_to_cpu(desc->wMaxPacketSize).
      This patch fix it up

      usb: gadget: convert all users to the new udc infrastructure · 0f91349b
      Sebastian Andrzej Siewior authored
      peripheral drivers are using usb_add_gadget()/usb_del_gadget() to
      register/unregister to the udc-core.
      
      The udc-core will take the first available gadget driver and attach
      function driver which is calling usb_gadget_register_driver(). This is
      the same behaviour we have right now.
      
      Only dummy_hcd was tested, the others were compiled tested.
