2019-12-13HID: asus: Ignore Asus vendor-page usage-code 0xff eventsHans de Goede
At least on a T100HA an Asus vendor-page usage-code 0xff event is send on every suspend and again on resume, resulting in the following warning: asus 0003:0B05:1807.0002: Unmapped Asus vendor usagepage code 0xff being logged twice on every suspend/resume. This commit silences the "Unmapped Asus vendor usagepage code ..." warning for usage-code 0xff to avoid these warnings being logged.

2019-12-13HID: ite: Add USB id match for Acer SW5-012 keyboard dockHans de Goede
The Acer SW5-012 2-in-1 keyboard dock uses a Synaptics S91028 touchpad which is connected to an ITE 8595 USB keyboard controller chip. This keyboard has the same quirk for its rfkill / airplane mode hotkey as other keyboards with the ITE 8595 chip, it only sends a single release event when pressed and released, it never sends a press event. This commit adds this keyboards USB id to the hid-ite id-table, fixing the rfkill key not working on this keyboard.

2019-12-13xen-blkback: prevent premature module unloadPaul Durrant
Objects allocated by xen_blkif_alloc come from the 'blkif_cache' kmem cache. This cache is destoyed when xen-blkif is unloaded so it is necessary to wait for the deferred free routine used for such objects to complete. This necessity was missed in commit 14855954f636 "xen-blkback: allow module to be cleanly unloaded". This patch fixes the problem by taking/releasing extra module references in xen_blkif_alloc/free() respectively.

2019-12-12clk: walk orphan list on clock provider registrationJerome Brunet
So far, we walked the orphan list every time a new clock was registered in CCF. This was fine since the clocks were only referenced by name. Now that the clock can be referenced through DT, it is not enough: * Controller A register first a reference clocks from controller B through DT. * Controller B register all its clocks then register the provider. Each time controller B registers a new clock, the orphan list is walked but it can't match since the provider is registered yet. When the provider is finally registered, the orphan list is not walked unless another clock is registered afterward. This can lead to situation where some clocks remain orphaned even if the parent is available. Walking the orphan list on provider registration solves the problem.

Commit 5e6669387e22 ("of/platform: Pause/resume sync state during init and of_platform_populate()") paused/resumed sync state during init only if Linux had parsed and populated a devicetree. However, the check for that (of_have_populated_dt()) can change after of_platform_default_populate_init() executes. One example of this is when devicetree unittests are enabled. This causes an unmatched pause/resume of sync state. To avoid this, just unconditionally pause/resume sync state during init.

2019-12-12IB/mlx5: Fix device memory flowsYishai Hadas
Fix device memory flows so that only once there will be no live mmaped VA to a given allocation the matching object will be destroyed. This prevents a potential scenario that existing VA that was mmaped by one process might still be used post its deallocation despite that it's owned now by other process. The above is achieved by integrating with IB core APIs to manage mmap/munmap. Only once the refcount will become 0 the DM object and its underlay area will be freed.

2019-12-12serial: sprd: Add clearing break interrupt operationYonghan Ye
A break interrupt will be generated if the RX line was pulled low, which means some abnomal behaviors occurred of the UART. In this case, we still need to clear this break interrupt status, otherwise it will cause irq storm to crash the whole system.

2019-12-12tty: serial: msm_serial: Fix lockup for sysrq and oopsLeo Yan
As the commit 677fe555cbfb ("serial: imx: Fix recursive locking bug") has mentioned the uart driver might cause recursive locking between normal printing and the kernel debugging facilities (e.g. sysrq and oops). In the commit it gave out suggestion for fixing recursive locking issue: "The solution is to avoid locking in the sysrq case and trylock in the oops_in_progress case." This patch follows the suggestion (also used the exactly same code with other serial drivers, e.g. amba-pl011.c) to fix the recursive locking issue, this can avoid stuck caused by deadlock and print out log for sysrq and oops.
