usb gadget: fix ethernet link reports to ethtool

2009-05-02T17:56:57+00:00

upstream commit: 237e75bf1e558f7330f8deb167fa3116405bef2c

The g_ether USB gadget driver currently decides whether or not there's a
link to report back for eth_get_link based on if the USB link speed is
set. The USB gadget speed is however often set even before the device is
enumerated. It seems more sensible to only report a "link" if we're
actually connected to a host that wants to talk to us. The patch below
does this for me - tested with the PXA27x UDC driver.

USB: add quirk to avoid config and interface strings

2009-05-02T17:56:35+00:00

upstream commit: 1662e3a7f076e51e3073faf9ce77157b529c475b

Apparently the Configuration and Interface strings aren't used as
often as the Vendor, Product, and Serial strings.  In at least one
device (a Saitek Cyborg Gold 3D joystick), attempts to read the
Configuration string cause the device to stop responding to Control
requests.

This patch (as1226) adds a quirks flag, telling the kernel not to
read a device's Configuration or Interface strings, together with a
new quirk for the offending joystick.

USB: gadget: fix rndis regression

2009-05-02T17:56:35+00:00

upstream commit: 090b90118207e786d2990310d063fda5d52cce6e

Restore some code that was wrongly dropped from the RNDIS
driver, and caused interop problems observed with OpenMoko.

The issue is with hardware which needs help conforming to part
of the USB 2.0 spec (section 8.5.3.2); some can automagically
send a ZLP in response to an unexpected IN, but not all chips
will do that.  We don't need to check the packet length ourselves
the way earlier code did, since the UDC must already check it.
But we do need to tell the UDC when it must force a short packet
termination of the data stage.

USB: usb-storage: increase max_sectors for tape drives

2009-05-02T17:56:34+00:00

'
upstream commit: 5c16034d73da2c1b663aa25dedadbc533b3d811c

This patch (as1203) increases the max_sector limit for USB tape
drives.  By default usb-storage sets max_sectors to 240 (i.e., 120 KB)
for all devices.  But tape drives need a higher limit, since tapes can
and do have very large block sizes.  Without the ability to transfer
an entire large block in a single command, such tapes can't be used.

This fixes Bugzilla #12207.

USB: fix USB_STORAGE_CYPRESS_ATACB

2009-05-02T17:56:33+00:00

upstream commit: 1f4159c1620f74377e26d8a569d10ca5907ef475

commit 64a87b24: [SCSI] Let scsi_cmnd->cmnd use request->cmd buffer
changed the scsi_eh_prep_cmnd logic by making it clear
the ->cmnd buffer. But the sat to cypress atacb translation supposed
the ->cmnd buffer wasn't modified.

This patch makes it set the ->cmnd buffer after scsi_eh_prep_cmnd call.
The problem and a fix was reported by Matthieu CASTET 

It also removes all the hackery fiddling of scsi_cmnd and scsi_eh_save by
requesting from scsi_eh_prep_cmnd to prepare a read into ->sense_buffer,
which is much more suitable a buffer for HW transfers, then after the command
execution the regs read is copied into regs buffer before actual preparation
of sense_buffer.

Also fix an alien comment character to my utf-8 editor.

USB: EHCI: add software retry for transaction errors

2009-05-02T17:56:33+00:00

upstream commit: a2c2706e1043c17139c2dafd171c4a5cf008ef7e

This patch (as1204) adds a software retry mechanism to ehci-hcd.  It
gets invoked when the driver encounters transaction errors on an
asynchronous endpoint.  On many systems, hardware deficiencies cause
such errors to occur if one device is unplugged while the host is
communicating with another device.  With the patch, the failed
transactions are retried and generally succeed the second or third
time through.

This is based on code originally written by Koichiro Saito.

USB: EHCI: Fix isochronous URB leak

2009-03-23T21:55:29+00:00

commit 508db8c954d55ed30f870d2c24d741ba6269d13c upstream.

ehci-hcd uses usb_get_urb() and usb_put_urb() in an unbalanced way causing
isochronous URB's kref.counts incrementing once per usb_submit_urb() call.
The culprit is *usb being set to NULL when usb_put_urb() is called after URB
is given back.
Due to other fixes there is no need for ehci-hcd to deal with usb_get_urb()
nor usb_put_urb() anymore, so patch removes their usages in ehci-hcd.
Patch also makes ehci_to_hcd(ehci)->self.bandwidth_allocated adjust, if a
stream finishes.
