3b48ece37e usb: gadget: align buffer size when allocating for OUT endpoint
commit e0466156ee2e944fb47a3fa00932c3698a6d2c67 upstream.

Using usb_ep_align() makes sure that the buffer size for OUT endpoints is
always aligned with wMaxPacketSize (512 usually). This makes sure
that no buffer has the wrong size, which can cause nasty bugs.

022a60e3bf usb: gadget: change len to size_t on alloc_ep_req()
commit 69bb99738b5c6d56d2b1a75db9cbb4d187453c1a upstream.

Length of buffers should be of type size_t whenever possible. Altough
recommended, this change has no real practical change, unless a driver has a
uses a huge or negative buffer size - it might help find these bugs.

commit 079fe5a6da616891cca1a26e803e1df2a87e9ae5 upstream.

This function is shared between gadget functions, so this avoid unnecessary
duplicated code and potentially avoid memory leaks.

We only support GPL drivers in the USB Gadget Framework,
it sounds correct to make all exported symbols GPL too.
