2019-03-08net: stmmac: Avoid one more sometimes uninitialized Clang warningNathan Chancellor
When building with -Wsometimes-uninitialized, Clang warns: drivers/net/ethernet/stmicro/stmmac/stmmac_ptp.c:111:2: error: variable 'ns' is used uninitialized whenever 'if' condition is false [-Werror,-Wsometimes-uninitialized] drivers/net/ethernet/stmicro/stmmac/stmmac_ptp.c:111:2: error: variable 'ns' is used uninitialized whenever '&&' condition is false [-Werror,-Wsometimes-uninitialized] Clang is concerned with the use of stmmac_do_void_callback (which stmmac_get_systime wraps), as it may fail to initialize these values if the if condition was ever false (meaning the callback doesn't exist). It's not wrong because the callback is what initializes ns. While it's unlikely that the callback is going to disappear at some point and make that condition false, we can easily avoid this warning by zero initializing the variable.

By default, the switch driver is expected to configure CPU and DSA ports to their maximum speed. For the 6341 and 6390 families, the ports interface mode has to be configured as well. The 6390X range support 10G ports using XAUI, while the 6341 and 6390 supports 2500BaseX, as their maximum speed.

2019-03-08vxlan: Fix GRO cells race condition between receive and link deleteStefano Brivio
If we receive a packet while deleting a VXLAN device, there's a chance vxlan_rcv() is called at the same time as vxlan_dellink(). This is fine, except that vxlan_dellink() should never ever touch stuff that's still in use, such as the GRO cells list. Otherwise, vxlan_rcv() crashes while queueing packets via gro_cells_receive(). Move the gro_cells_destroy() to vxlan_uninit(), which runs after the RCU grace period is elapsed and nothing needs the gro_cells anymore. This is now done in the same way as commit 8e816df87997 ("geneve: Use GRO cells infrastructure.") originally implemented for GENEVE.

2019-03-08clk: ti: clkctrl: Fix clkdm_name regression for TI_CLK_CLKCTRL_COMPATTony Lindgren
Commit a72d785021cb ("clk: ti: Prepare for remove of OF node name") changed the code to use kasprintf() for provider->clkdm_name but also changed the offset used later on by three. We don't need to change the offset as we already have the extra three characters in the format for kasprintf with "%pOFnxxx". This caused the clocks with TI_CLK_CLKCTRL_COMPAT to have NULL clk->clkdm_name for omap4 and 5. And null clkdm_name can cause module reset, enable, and idle to fail. The issue can also be seen also when enabling DEBUG for clkctrl.c and then we start seeing "clock: could not associate" messages for omap4 and 5 as the generated name is something like "l4_wkclkdm" instead of "l4_wkup_clkdm" that's needed. Let's fix the issue with a partial revert of commit a72d785021cb ("clk: ti: Prepare for remove of OF node name"). ALso note that in general code should not depend on the dts node names. And the node names should be generic types like clock-domain in this case. This could be fixed later by using separate compatible properties for the clockdomains, or by adding soc_device_match() table with reg offsets to the driver. But let's fix the regression first.

2019-03-08clk: fixup default index for of_clk_get_by_name()Kuninori Morimoto
of_clk_get_by_name() is using -1 for __of_clk_get() index. It will go to of_parse_clkspec(), and be used for of_parse_phandle_with_args(). Here, if user doesn't specify clock name (= of_clk_get_by_name(np, NULL)), this index is still -1, and of_parse_phandle_with_args() will return -EINVAL (This index will be updated if if it had clock name). clk_get_by_name(np, NULL) should work, then, default index should be 0 instead of -1. This patch fixes it.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v5.1 cycle: Core changes: - The big change this time around is the irqchip handling in the qualcomm pin controllers, closely coupled with the gpiochip. This rework, in a classic fall-between-the-chairs fashion has been sidestepped for too long. The Qualcomm IRQchips using the SPMI and SSBI transport mechanisms have been rewritten to use hierarchical irqchip. This creates the base from which I intend to gradually pull support for hierarchical irqchips into the gpiolib irqchip helpers to cut down on duplicate code. We have too many hacks in the kernel because people have been working around the missing hierarchical irqchip for years, and once it was there, noone understood it for a while. We are now slowly adapting to using it. This is why this pull requests include changes to MFD, SPMI, IRQchip core and some ARM Device Trees pertaining to the Qualcomm chip family. Since Qualcomm have so many chips and such large deployments it is paramount that this platform gets this right, and now it (hopefully) does. - Core support for pull-up and pull-down configuration, also from the device tree. When a simple GPIO chip supports an "off or on" pull-up or pull-down resistor, we provide a way to set this up using machine descriptors or device tree. If more elaborate control of pull up/down (such as resistance shunt setting) is required, drivers should be phased over to use pin control. We do not yet provide a userspace ABI for this pull up-down setting but I suspect the makers are going to ask for it soon enough. PCA953x is the first user of this new API. - The GPIO mockup driver has been revamped after some discussion improving the IRQ simulator in the process. The idea is to make it possible to use the mockup for both testing and virtual prototyping, e.g. when you do not yet have a GPIO expander to play with but really want to get something to develop code around before hardware is available. It's neat. The blackbox testing usecase is currently making its way into kernelci. - ACPI GPIO core preserves non direction flags when updating flags. - A new device core helper for devm_platform_ioremap_resource() is funneled through the GPIO tree with Greg's ACK. New drivers: - TQ-Systems QTMX86 GPIO controllers (using port-mapped I/O) - Gateworks PLD GPIO driver (vaccumed up from OpenWrt) - AMD G-Series PCH (Platform Controller Hub) GPIO driver. - Fintek F81804 & F81966 subvariants. - PCA953x now supports NXP PCAL6416. Driver improvements: - IRQ support on the Nintendo Wii (Hollywood) GPIO. - get_direction() support for the MVEBU driver. - Set the right output level on SAMA5D2. - Drop the unused irq trigger setting on the Spreadtrum driver. - Wakeup support for PCA953x. - A slew of cleanups in the various Intel drivers" * tag 'gpio-v5.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (110 commits) gpio: gpio-omap: fix level interrupt idling gpio: amd-fch: Set proper output level for direction_output x86: apuv2: remove unused variable gpio: pca953x: Use PCA_LATCH_INT platform/x86: fix PCENGINES_APU2 Kconfig warning gpio: pca953x: Fix dereference of irq data in shutdown gpio: amd-fch: Fix type error found by sparse gpio: amd-fch: Drop const from resource gpio: mxc: add check to return defer probe if clock tree NOT ready gpio: ftgpio: Register per-instance irqchip gpio: ixp4xx: Add DT bindings x86: pcengines apuv2 gpio/leds/keys platform driver gpio: AMD G-Series PCH gpio driver drivers: depend on HAS_IOMEM for devm_platform_ioremap_resource() gpio: tqmx86: Set proper output level for direction_output gpio: sprd: Change to use SoC compatible string gpio: sprd: Use SoC compatible string instead of wildcard string gpio: of: Handle both enable-gpio{,s} gpio: of: Restrict enable-gpio quirk to regulator-gpio gpio: davinci: use devm_platform_ioremap_resource() ...

2019-03-08drm/i915: Relax mmap VMA checkTvrtko Ursulin
Legacy behaviour was to allow non-page-aligned mmap requests, as does the linux mmap(2) implementation by virtue of automatically rounding up for the caller. To avoid breaking legacy userspace relax the newly introduced fix.

2019-03-08drm/i915: Acquire breadcrumb ref before cancellingChris Wilson
We may race the interrupt signaling with retirement, in which case the order in which we acquire the reference inside the interrupt is vital to provide the correct barrier against the request being freed in retirement, i.e. we need to acquire our reference before marking the breadcrumb as cancelled (as soon as the breadcrumb is cancelled retirement may drop its reference to the request without serialisation with the interrupt handler). <3>[ 683.372226] BUG i915_request (Tainted: G U ): Object already free <3>[ 683.372269]

2019-03-08drm/i915: Reacquire priolist cache after dropping the engine lockChris Wilson
If we drop the engine lock, we may run execlists_dequeue which may free the priolist. Therefore if we ever drop the execution lock on the engine, we have to discard our cache and refetch the priolist to ensure we do not use a stale pointer.

2019-03-08drm/i915: Protect i915_active iterators from the shrinkerChris Wilson
If we allocate while iterating the rbtree of active nodes, we may hit the shrinker and so retire the i915_active, reaping the rbtree. Modifying the rbtree as we iterate is not good behaviour, so acquire the i915_active first to keep the tree intact whenever we allocate.

2019-03-08drm/i915: HDCP state handling in ddi_update_pipeRamalingam C
The downgrade of the fullmodeset into fastset intel_encoder->update_pipe, in possible scenario, skips the En/Dis-able DDI. Hence breaks the HDCP state change handling. We also don't have any hdcp tests in CI, because the shard runs don't have hdcp capable outputs :-/ So this change fixs it by handling the HDCP state change request at intel_encoder->update_pipe too along with enable and disable of the DDI.
