2014-11-07USB: storage: Reject bogus max LUN valuesMark Knibbs1-3/+14
Some mass storage devices return a bogus value in response to a Get Max LUN request. The Iomega Jaz USB Adapter responds with 0x10, hence my recent patch to use the US_FL_SINGLE_LUN quirk for it. The USB MSC Bulk Only Transport document says "The device shall return one byte of data that contains the maximum LUN supported by the device." Since the LUN field in the command block wrapper is only 4 bits wide, it might be helpful to report too-large LUN values in the kernel log, and assume max LUN is actually 0. That could get some devices which currently need the US_FL_SINGLE_LUN quirk to work.

2014-11-06usb: gadget: f_hid: convert to new function interface with backward compatibilityAndrzej Pietrasiewicz5-32/+227
Converting hid to the new function interface requires converting the USB hid's function code and its users. This patch converts the f_hid.c to the new function interface. The file can now be compiled into a separate usb_f_hid.ko module. The old function interface is provided by means of a preprocessor conditional directives. After all users are converted, the old interface can be removed. Signed-off-by: Andrzej Pietrasiewicz <andrzej.p@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

2014-11-06USB: cdc-acm: add quirk for control-line state requestsJohan Hovold2-2/+14
Add new quirk for devices that cannot handle control-line state requests. Note that we currently send these requests to all devices, regardless of whether they claim to support it, but that errors are only logged if support is claimed. Since commit 0943d8ead30e ("USB: cdc-acm: use tty-port dtr_rts"), which only changed the timings for these requests slightly, this has been reported to cause occasional firmware crashes on Simtec Electronics Entropy Key devices after re-enumeration. Enable the quirk for this device.

2014-11-05usb: gadget: f_midi: enable use of the index parameterAndrzej Pietrasiewicz1-1/+1
The soundcard index to use for the ALSA device creation is passed as a parameter to f_midi_bind_config(), but is assigned to midi->index only after the call to f_midi_register_card(midi). So no matter what is passed to f_midi_bind_config(), the actual index for snd_card_new() is always 0. This probably works ok if at the moment of f_midi's bind there are no other snd_cards, but if there are, it is not possible to bind f_midi. This patch moves the assignment to a place before the call to f_midi_register_card(midi). Signed-off-by: Andrzej Pietrasiewicz <andrzej.p@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
