hwmon: (it87) Fix VID reading on IT8718F

2009-12-08T19:17:33Z

commit 371dc4a6d8c3c74a9a1c74b87c2affb3fcef6500 upstream Comparing apples to bananas doesn't seem right. The bug has been there since support for the IT8718F was added, so VID never worked for this chip. Signed-off-by: Jean Delvare Signed-off-by: Greg Kroah-Hartman

dca: redesign locks to fix deadlocks

2009-12-08T19:17:31Z

commit eb4400e3a040b90a3ad805b01fcbc99a5f615c8f upstream. Change spin_locks to irqsave to prevent dead-locks. Protect adding and deleting to/from dca_providers list. Drop the lock during dca_sysfs_add_req() and dca_sysfs_remove_req() calls as they might sleep (use GFP_KERNEL allocation).

USB: usb-serial: replace shutdown with disconnect, release

2009-12-08T19:17:31Z

This is commit f9c99bb8b3a1ec81af68d484a551307326c2e933 back-ported to 2.6.27.39. This patch (as1254-2) splits up the shutdown method of usb_serial_driver into a disconnect and a release method. The problem is that the usb-serial core was calling shutdown during disconnect handling, but drivers didn't expect it to be called until after all the open file references had been closed. The result was an oops when the close method tried to use memory that had been deallocated by shutdown. Signed-off-by: Alan Stern Tested-by: Rory Filer Signed-off-by: Greg Kroah-Hartman

USB: suspend/resume support for option driver

2009-12-08T19:17:28Z

commit 4901b2c34ecb6fc45909228ad269c8126efe4401 upstream. This patch implements suspend and resume methods for the option driver. With my hardware I can even suspend the system and keep up a connection for a short time. Signed-off-by: Oliver Neukum Signed-Off-By: Matthias Urlichs Signed-off-by: Greg Kroah-Hartman

USB: ohci: quirk AMD prefetch for USB 1.1 ISO transfer

2009-12-08T19:17:27Z

commit a1f17a872bc7b1cb7efdd5486a2963e88a536e61 upstream. The following patch in the driver is required to avoid USB 1.1 device failures that may occur due to requests from USB OHCI controllers may be overwritten if the latency for any pending request by the USB controller is very long (in the range of milliseconds).

fuse: prevent fuse_put_request on invalid pointer

2009-12-08T19:17:21Z

commit f60311d5f7670d9539b424e4ed8b5c0872fc9e83 upstream. fuse_direct_io() has a loop where requests are allocated in each iteration. if allocation fails, the loop is broken out and follows into an unconditional fuse_put_request() on that invalid pointer.

fuse: reject O_DIRECT flag also in fuse_create

2009-12-08T19:17:19Z

commit 1b7323965a8c6eee9dc4e345a7ae4bff1dc93149 upstream. The comment in fuse_open about O_DIRECT: "VFS checks this, but only _after_ ->open()" also holds for fuse_create, however, the same kind of check was missing there. As an impact of this bug, open(newfile, O_RDWR|O_CREAT|O_DIRECT) fails, but a stub newfile will remain if the fuse server handled the implied FUSE_CREATE request appropriately. Other impact: in the above situation ima_file_free() will complain to open/free imbalance if CONFIG_IMA is set.
