git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc Pull powerpc updates from Benjamin Herrenschmidt: "Notable highlights: - iommu improvements from Anton removing the per-iommu global lock in favor of dividing the DMA space into pools, each with its own lock, and hashed on the CPU number. Along with making the locking more fine grained, this gives significant improvements in multiqueue networking scalability. - Still from Anton, we know provide a vdso based variant of getcpu which makes sched_getcpu with the appropriate glibc patch something like 18 times faster. - More anton goodness (he's been busy !) in other areas such as a faster __clear_user and copy_page on P7, various perf fixes to improve sampling quality, etc... - One more step toward removing legacy i2c interfaces by using new device-tree based probing of platform devices for the AOA audio drivers - A nice series of patches from Michael Neuling that helps avoiding confusion between register numbers and litterals in assembly code, trying to enforce the use of "%rN" register names in gas rather than plain numbers. - A pile of FSL updates - The usual bunch of small fixes, cleanups etc... You may spot a change to drivers/char/mem. The patch got no comment or ack from outside, it's a trivial patch to allow the architecture to skip creating /dev/port, which we use to disable it on ppc64 that don't have a legacy brige. On those, IO ports 0...64K are not mapped in kernel space at all, so accesses to /dev/port cause oopses (and yes, distros -still- ship userspace that bangs hard coded ports such as kbdrate)." * 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc: (106 commits) powerpc/mpic: Create a revmap with enough entries for IPIs and timers Remove stale .rej file powerpc/iommu: Fix iommu pool initialization powerpc/eeh: Check handle_eeh_events() return value powerpc/85xx: Add phy nodes in SGMII mode for MPC8536/44/72DS & P2020DS powerpc/e500: add paravirt QEMU platform powerpc/mpc85xx_ds: convert to unified PCI init powerpc/fsl-pci: get PCI init out of board files powerpc/85xx: Update corenet64_smp_defconfig powerpc/85xx: Update corenet32_smp_defconfig powerpc/85xx: Rename P1021RDB-PC device trees to be consistent powerpc/watchdog: move booke watchdog param related code to setup-common.c sound/aoa: Adapt to new i2c probing scheme i2c/powermac: Improve detection of devices from device-tree powerpc: Disable /dev/port interface on systems without an ISA bridge of: Improve prom_update_property() function powerpc: Add "memory" attribute for mfmsr() powerpc/ftrace: Fix assembly trampoline register usage powerpc/hw_breakpoints: Fix incorrect pointer access powerpc: Put the gpr save/restore functions in their own section ...

2012-07-24leds-lp5523: BUG() in error handling in probe()Dan Carpenter
Inside the error handling in lp5523_init_led(), there is a place that calls to led_classdev_unregister(). When we unregister the LED drivers, it tries to set the brightness to OFF. In this driver setting the brightness is done through a work queue and the work queue hasn't been initialized yet. The result is that we trigger a WARN_ON() in the __queue_work(). The fix is to move the INIT_WORK() in front of the call to lp5523_init_led(). Matt Renzelmann found this using a bug finding tool.

Fix led_trigger_event() to use led_set_brightness() instead of __led_set_brightness(), so that any pending blink timer is stopped before setting the new brightness value. Without this fix LED status may be overridden by a pending timer. This allows a trigger to use a mix of led_trigger_event(), led_trigger_blink() and led_trigger_blink_oneshot() without races.

2012-07-24leds: fix led_brightness_set when soft-blinkingFabio Baltieri
Move led_stop_software_blink() code into led_brightness_set() to ensure software blink timer is stopped and cleared when changing trigger. Also use led_set_brightness() instead of calling led_cdev->brightness_set() directly to keep led_cdev->brightness consistent with current LED status. This ensure proper cleaning when changing triggers, as without this fix a LED may be turned off while leaving it's led_cdev->brightness = 1, leading to an erratic software-blink behaviour. The problem was easy to reproduce by changing the trigger from "timer" to "oneshot". Signed-off-by: Fabio Baltieri <fabio.baltieri@gmail.com> Signed-off-by: Bryan Wu <bryan.wu@canonical.com>
