      usb: musb: avoid NULL pointer dereference · eee3f15d
      Felipe Balbi authored 
      instead of relying on the otg pointer, which
can be NULL in certain cases, we can use the
gadget and host pointers we already hold inside
struct musb.

      usb: dwc3: fix wrong bit mask in dwc3_event_devt · 06f9b6e5
      Huang Rui authored 
      Around DWC USB3 2.30a release another bit has been added to the
Device-Specific Event (DEVT) Event Information (EvtInfo) bitfield.

Because of that, what used to be 8 bits long, has become 9 bits long.

Per dwc3 2.30a+ spec in the Device-Specific Event (DEVT), the field of
Event Information Bits(EvtInfo) uses [24:16] bits, and it has 9 bits
not 8 bits. And the following reserved field uses [31:25] bits not
[31:24] bits, and it has 7 bits.

So in dwc3_event_devt, the bit mask should be:
event_info	[24:16]		9 bits
reserved31_25	[31:25]		7 bits

This patch makes sure that newer core releases will work fine with
Linux and that we will decode the event information properly on new
core releases.

      usb: gadget: gr_udc: remove some unneeded error handling · 798a2468
      Dan Carpenter authored 
      Debugfs function return an ERR_PTR if they compiled out.  We don't need
to test for that here because if the debugfs file are compiled out then
it is ok to pass an ERR_PTR to debugfs_create_file() since it will just
be a no-op stub.

Debugfs return NULLs on error, but we don't need to test for that either
because debugfs_create_file() will accept NULL pointers.
