* USB: ffs-test: fix header pathDavidlohr Bueso2011-02-28
| | | | | | | | | | | When compiling this program the functionfs.h header cannot be found, producing: ffs-test.c:40: fatal error: linux/usb/functionfs.h: No such file or directory This patch also fixes the following warning: ffs-test.c:453: warning: format ‘%4d’ expects type ‘int’, but argument 3 has type ‘size_t’ Signed-off-by: Davidlohr Bueso <dave@gnu.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* USB: serial/kobil_sct, fix potential tty NULL dereferenceJiri Slaby2011-02-28
| | | | | | | | | | | | Make sure that we check the return value of tty_port_tty_get. Sometimes it may return NULL and we later dereference that. The only place here is in kobil_read_int_callback, so fix it.

| | | | | | | | | | | | | 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.

| | | | | | | | | | | 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.

* USB: serial drivers need to use larger bulk-in buffersAlan Stern2011-02-25
| | | | | | | | | | | | | | | | | | | 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.

* USB: use "device number" instead of "address"Alan Stern2011-02-25
| | | | | | | | | | | | | | | | | | 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.

* usb: musb: OMAP4430: Fix usb device detection if connected during bootHema HK2011-02-18
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

If we don't have OTG, there's no point of leaving MUSB prepared for operation if a gadget driver fails to probe.
