rt2x00: error in configurations with mesh support disabled

2013-03-28T19:18:14Z

commit 6ef9e2f6d12ce9e2120916804d2ddd46b954a70b upstream. If CONFIG_MAC80211_MESH is not set, cfg80211 will now allow advertising interface combinations with NL80211_IFTYPE_MESH_POINT present. Add appropriate ifdefs to avoid running into errors. [Backported for 3.8-stable. Removed code of simultaneous AP and mesh mode added in 4a5fc6d 3.9-rc1.] Signed-off-by: Felix Fietkau Acked-by: Gertjan van Wingerde Signed-off-by: John W.

usb: musb: da8xx: Fix build breakage due to typo

2013-03-28T19:18:14Z

commit db9e51617faad3a54d10b7cb340a82688ec0232d upstream. Commit 032ec49f5351e9cb242b1a1c367d14415043ab95 (usb: musb: drop useless board_mode usage) introduced a typo that breaks the build.

USB: io_ti: fix get_icount for two port adapters

2013-03-28T19:18:14Z

commit 5492bf3d5655b4954164f69c02955a7fca267611 upstream. Add missing get_icount field to two-port driver. The two-port driver was not updated when switching to the new icount interface in commit 0bca1b913aff ("tty: Convert the USB drivers to the new icount interface").

USB: garmin_gps: fix memory leak on disconnect

2013-03-28T19:18:14Z

commit 618aa1068df29c37a58045fe940f9106664153fd upstream. Remove bogus disconnect test introduced by 95bef012e ("USB: more serial drivers writing after disconnect") which prevented queued data from being freed on disconnect. The possible IO it was supposed to prevent is long gone. Signed-off-by: Johan Hovold Signed-off-by: Greg Kroah-Hartman

ACPI: Rework acpi_get_child() to be more efficient

2013-03-28T19:18:14Z

commit 33f767d767e9a684e9cd60704d4c049a2014c8d5 upstream. Observe that acpi_get_child() doesn't need to use the helper struct acpi_find_child structure and change it to work without it. Also, using acpi_get_object_info() to get the output of _ADR for the given device is overkill, because that function does much more than just evaluating _ADR (let alone the additional memory allocation done by it). Moreover, acpi_get_child() doesn't need to loop any more once it has found a matching handle, so make it stop in that case. To prevent the results from changing, make it use do_acpi_find_child() as a post-order callback. Signed-off-by: Rafael J. Wysocki Cc: Josh Boyer Signed-off-by: Greg Kroah-Hartman

efivars: Fix check for CONFIG_EFI_VARS_PSTORE_DEFAULT_DISABLE

efivars: Add module parameter to disable use as a pstore backend

2013-03-28T19:18:13Z

commit ec0971ba5372a4dfa753f232449d23a8fd98490e upstream. We know that with some firmware implementations writing too much data to UEFI variables can lead to bricking machines. Recent changes attempt to address this issue, but for some it may still be prudent to avoid writing large amounts of data until the solution has been proven on a wide variety of hardware. Crash dumps or other data from pstore can potentially be a large data source. Add a pstore_module parameter to efivars to allow disabling its use as a backend for pstore. Also add a config option, CONFIG_EFI_VARS_PSTORE_DEFAULT_DISABLE, to allow setting the default value of this paramter to true (i.e. disabled by default).

efivars: Allow disabling use as a pstore backend

2013-03-28T19:18:12Z

commit ed9dc8ce7a1c8115dba9483a9b51df8b63a2e0ef upstream. Add a new option, CONFIG_EFI_VARS_PSTORE, which can be set to N to avoid using efivars as a backend to pstore, as some users may want to compile out the code completely. Set the default to Y to maintain backwards compatability, since this feature has always been enabled until now.

USB: serial: fix interface refcounting

2013-03-28T19:18:06Z

commit d7971051e4df825e0bc11b995e87bfe86355b8e5 upstream. Make sure the interface is not released before our serial device. Note that drivers are still not allowed to access the interface in any way that may interfere with another driver that may have gotten bound to the same interface after disconnect returns.

usb: gadget: ffs: fix enable multiple instances

2013-03-28T19:18:02Z

commit 3416905ba058e43112ad7b1b4859797f027f5a07 upstream. This patch fixes an "off-by-one" bug found in 581791f (FunctionFS: enable multiple functions). During gfs_bind/gfs_unbind the functionfs_bind/functionfs_unbind should be called for every functionfs instance. With the "i" pre-decremented they were not called for the zeroth instance.
