2008-11-13ub: stub pre_reset and post_reset to fix oopsPete Zaitcev

Worse, this deadlocks keventd and this takes whole box down. I'm going to fix this properly later, but let's unbreak the driver quickly for non-composite devices at least.

Fixes co-working issue of usb serial device with usb/net devices while oter endpoints are free and can be used.This patch implements the policy that if endpoint resources are available then different BULK request goes to different endpoint otherwise they are multiplexed to one reserved endpoint as currently done. Switch statement case is reordered in musb_giveback() to take care of bulk request both in multiplex scenario and otherwise. NAK limit scheme has to be added for multiplexed BULK request scenario to avoid endpoint starvation due to usb/net devices.

2008-11-13USB: don't register endpoints for interfaces that are going awayAlan Stern
This patch (as1155) fixes a bug in usbcore. When interfaces are deleted, either because the device was disconnected or because of a configuration change, the extra attribute files and child endpoint devices may get left behind. This is because the core removes them before calling device_del(). But during device_del(), after the driver is unbound the core will reinstall altsetting 0 and recreate those extra attributes and children. The patch prevents this by adding a flag to record when the interface is in the midst of being unregistered. When the flag is set, the attribute files and child devices will not be created.

2008-11-12adt7462: new hwmon driverDarrick J. Wong
New driver to play with. As Jean mentioned a couple of years ago, this chip is a beast with odd combinations of 8 fans, 4 temperatures, and 13 voltage sensors. This driver has been tested on an IntelliStation Z30. Signed-off-by: Darrick J.

2008-11-12LIS3LV02Dx Accelerometer driverPavel Machek
This adds a driver to the accelerometer sensor found in several HP laptops (under the commercial names of "HP Mobile Data Protection System 3D" and "HP 3D driveguard"). It tries to have more or less the same interfaces as the hdaps and other accelerometer drivers: in sysfs and as a joystick. This driver was first written by Yan Burman. Eric Piel has updated it and slimed it up (including the removal of an interface to access to the free-fall feature of the sensor because it is not reliable enough for now). Pavel Machek removed few more features and switched locking from semaphore to mutex. Several people have contributed to the database of the axes.

2008-11-12atmel_spi: work-around required for new HW bug in AT91SAM9263 Rev.B SPI ↵Jean-Christophe Lallemand
controller We're working with an AT91SAM9263 Rev B in our design and I experienced some inconsistency in spi-based touchscreen usage between our board and the Atmel evaluation kit we have that runs on a Rev A chip. The data was apparently delayed by 1 byte and got ridiculous data out of the touchscreen driver, very strange. As everything looked normal in the spi, touchscreen and dma logs, I contacted the Atmel support and they triggered me on a new HW bug that appeared in the Rev B SPI controller. The problem is that the SPI controller on the Rev B needs that the software reset is performed two times so that it's performed correctly. Applying the patch below solves the issue on my Rev B board. I've tested it as well on my Rev A evaluation kit and it has apparently no unwanted side effect, things continue to work as expected.

2008-11-12i5000-edac: hold reference to mci kobjectDarrick J. Wong
It turns out that edac_mc_del_mc will kobject_put the last kref on the mci object. If the timing is just right, that means that the mci object is freed before before i5000_remove_one has a chance to free the resources associated with it, causing a null pointer exceptions when unloading the driver. Insert a kobject_{get,put} pair so that this doesn't happen. Signed-off-by: Darrick J.
