Make sure that we check the return value of tty_port_tty_get. Sometimes it may return NULL and we later dereference that. There are several places to check. For easier handling, tty_port_tty_get is moved directly to the palce where needed in keyspan_pda_rx_interrupt. Signed-off-by:

Consolidate printouts to use dev_XXX functions instead of an assortment of printks and driver specific macros. Remove some unused code snippets and struct members. Remove some unused function parameters and #defines. Change the "queue_entry" variable name which has different but related meanings in different places and use "slot" only. Signed-off-by:

This helps users with platform-bus-connected isp176xs, big-endian cpu, and missing byteswapping on the data bus. It does so by collecting all SW byteswaps in one place and also fixes a bug with non-32-bit io transfers on this hardware, where payload has to be byteswapped instead of ptds. Signed-off-by:

When a driver doesn't know how much data a device is going to send, the buffer size should be at least as big as the endpoint's maxpacket value. The serial drivers don't follow this rule; many of them request only 256-byte bulk-in buffers. As a result, they suffer overflow errors if a high-speed device wants to send a lot of data, because high-speed bulk endpoints are required to have a maxpacket size of 512. This patch (as1450) fixes the problem by using the driver's bulk_in_size value as a minimum, always allocating buffers no smaller than the endpoint's maxpacket size. Signed-off-by:

The USB stack historically has conflated device numbers (i.e., the value of udev->devnum) with device addresses. This is understandable, because until recently the two values were always the same. But with USB-3.0 they aren't the same, so we should start calling these things by their correct names. This patch (as1449b) changes many of the references to "address" in the hub driver to "device number" or "devnum". The patch also removes some unnecessary or misleading comments. Signed-off-by:

If a device plug/unplug is detected on an ATI SB700 USB controller in D3, it appears to set the port status register but not the controller status register. As a result we'll fail to detect the plug event. Check the port status register on resume as well in order to catch this case. Signed-off-by:

In the gadget code, there are several DBG() macro invocations that explicitly print the calling function's name while DBG() macro itself does this anyway; most of these were added by commit f11d893d (usb: musb: support ISO high bandwidth for gadget mode). Remove the duplicated printing, somewhat clarifying the messages at the same time... Signed-off-by:

OMAP4430 is embedded with UTMI PHY. This PHY does not support the OTG features like ID pin detection and VBUS detection. This function is exported to an external companion chip TWL6030. Software must retrieve the OTG HNP and SRP status from the TWL6030 and configure the bits inside the control module that drive the related USBOTGHS UTMI interface signals. It must also read back the UTMI signals needed to configure the TWL6030 OTG module. Can find more details in the TRM[1]. [1]:http://focus.ti.com/pdfs/wtbu/OMAP4430_ES2.0_Public_TRM_vJ.pdf In OMAP4430 musb driver VBUS and ID notifications are received from the transceiver driver. If the cable/device is connected during boot, notifications from transceiver driver will be missed till musb driver is loaded. Patch to configure the transceiver in the platform_enable/disable functions and enable the vbus in the gadget driver based on the last_event of the otg_transceiver. Signed-off-by:

Just a few cosmetic fixes to usb_gadget_probe_driver() and usb_gadget_unregister_driver(). Decreased a few indentation levels with goto statements. While at that, also add the missing call to musb_stop(). If we don't have OTG, there's no point of leaving MUSB prepared for operation if a gadget driver fails to probe. The same is valid for usb_gadget_unregister_driver(), since we are removing the gadget driver and we don't have OTG, we can completely unconfigure MUSB. Signed-off-by: -
