[PATCH] RDMA/ucma: Allow resolving address without specifying source address

by Roland Dreier

From: Roland Dreier <roland(a)purestorage.com> The RDMA CM will select a source device and address by consulting the routing table if no source address is passed into rdma_resolve_address(). Userspace will ask for this by passing an all-zero source address in the RESOLVE_IP command. Unfortunately the new check for non-zero address size rejects this with EINVAL, which breaks valid userspace applications. Fix this by explicitly allowing a zero address family for the source.

[PATCH v2] platform/x86: asus-wireless: Fix NULL pointer dereference

by João Paulo Rechi Vita

When the module is removed the led workqueue is destroyed in the remove callback, before the led device is unregistered from the led subsystem. This leads to a NULL pointer derefence when the led device is unregistered automatically later as part of the module removal cleanup. Bellow is the backtrace showing the problem.

[PATCH] ARM: dts: da850-lego-ev3: Fix battery voltage gpio

by David Lechner

This fixes the battery voltage monitoring gpio-hog settings. When the gpio is low, it turns off the battery voltage to the ADC chip. However, this needs to be on all of the time so that we can monitor battery voltage. Also, there was a typo that prevented pinmuxing from working correctly. Signed-off-by: David Lechner <david(a)lechnology.com> Signed-off-by: Sekhar Nori <nsekhar(a)ti.com> --- This has already been picked up in mainline in 4.15 (c5a88cd2e1c5). However, I forgot to cc stable when I originally submitted the patch.
