USB: usbserial - fix potential deadlock between write() and IRQ usb_serial_generic_write() doesn't disable interrupts when taking port->lock, and could therefore deadlock with usb_serial_generic_read_bulk_callback() being called from interrupt, taking the same lock. Fix it. Signed-off-by:

the disconnect method of this driver set intfdata to NULL before removing attribute files. The attributes' read methods will happily follow the NULL pointer. Here's the correct ordering. Signed-off-by : Oliver Neukum <oneukum@suse.de> Signed-off-by: -

Pete caused me to lock at buggy drivers in this respect. The idmouse has a race between open and disconnect. This patch - solves the open/disconnect race - switches locking to mutexes Signed-off-by:

This patch (as1005) fixes a rather subtle problem. When usb_set_configuration() registers the interfaces and their files in sysfs, it doesn't expect those files to exist already. But when an interface is registered, its driver may call usb_set_interface() and thereby cause the sysfs files to be created. The result is an error when usb_set_configuration() goes on to create those same files again. The (not-so-great) solution is to have usb_set_configuration() remove any existing files before creating them. Signed-off-by:

fix ssb_ohci_probe() build bug: drivers/built-in.o: In function `ssb_ohci_probe': ohci-hcd.c:(.text+0xbff39): undefined reference to `ssb_device_enable' ohci-hcd.c:(.text+0xbff6f): undefined reference to `ssb_admatch_base' ohci-hcd.c:(.text+0xbff8b): undefined reference to `ssb_admatch_size' ohci-hcd.c:(.text+0xbffe5): undefined reference to `ssb_device_disable' [...] the reason was that this Kconfig combination was allowed: CONFIG_SSB=m CONFIG_USB_OHCI_HCD=y CONFIG_USB_OHCI_HCD_SSB=y the fix is to require a modular USB_OHCI_HCD build when SSB is modular.

The Coverity checker spotted that we have already oops'ed if "dev" was NULL in these places. Since "dev" being NULL isn't possible at these places this patch removes the NULL checks. Additionally, I've fixed the formatting of the if's. Signed-off-by:

The ISD200 driver imports a single trivial routine from the IDE layer and in doing so creates a mess of dependancies that drag in the entire old IDE layer. Even more sad - it does this for a routine which is usually (little endian) a null function! - Copy the function into ISD200 - Rename it so it doesn't clash with the ide header prototype - Remove all the depend constraints Signed-off-by:

This patch (as1003) changes uhci-hcd to treat the URB_ISO_ASAP flag the same as other host controller drivers, namely, to schedule an Iso URB for the first available time slot that hasn't already expired. URBs in which the flag isn't set will be scheduled for the first slot following the last URB, even if it has expired. This fixes a problem reported by Martin Bachem. Signed-off-by:

The ch341 currently doesn't support most of the hardware setting. So to keep the termios data right we propogate the old termios hardware values back then encode the speed. Signed-off-by:

The patch is big. Really big. You just won't believe how vastly hugely mindbogglingly big it is. I mean you may think it's a long way down the road to the chemist, but that's just peanuts to how big the patch from 2.6.23 is. But it's all good.
