usb: gadget: function: f_obex: fix Interface Descriptor Test 2014-10-20T20:58:49+00:00 Felipe Balbi balbi@ti.com 2014-09-29T20:18:20+00:00 3985f3ab0834edf014ebd19192d9dd77422dea67 On USB20CV's Interface Descriptor Test, a series of SetInterface/GetInterface requests are issued and gadget driver is required to always return correct alternate setting. In one step of the test, g_serial with f_obex was returning the wrong value (1 instead of 0). In order to fix this, we will now hold currently selected alternate setting inside our struct f_obex and just return that from our ->get_alt() implementation. Note that his also simplifies the code a bit. Signed-off-by: Felipe Balbi <balbi@ti.com> 
On USB20CV's Interface Descriptor Test, a series
of SetInterface/GetInterface requests are issued
and gadget driver is required to always return
correct alternate setting.

In one step of the test, g_serial with f_obex
was returning the wrong value (1 instead of 0).

In order to fix this, we will now hold currently
selected alternate setting inside our struct f_obex
and just return that from our ->get_alt()
implementation.
