2020-11-06USB: apple-mfi-fastcharge: fix reference leak in apple_mfi_fc_set_propertyZhang Qilong1-1/+3
pm_runtime_get_sync() will increment pm usage at first and it will resume the device later. If runtime of the device has error or device is in inaccessible state(or other error state), resume operation will fail. If we do not call put operation to decrease the reference, the result is that this device cannot enter the idle state and always stay busy or other non-idle state.

2020-11-06staging: ralink-gdma: fix kconfig dependency bug for DMA_RALINKNecip Fazil Yildiran1-0/+1
When DMA_RALINK is enabled and DMADEVICES is disabled, it results in the following Kbuild warnings: WARNING: unmet direct dependencies detected for DMA_ENGINE Depends on [n]: DMADEVICES [=n] Selected by [y]: - DMA_RALINK [=y] && STAGING [=y] && RALINK [=y] && !SOC_RT288X [=n] WARNING: unmet direct dependencies detected for DMA_VIRTUAL_CHANNELS Depends on [n]: DMADEVICES [=n] Selected by [y]: - DMA_RALINK [=y] && STAGING [=y] && RALINK [=y] && !SOC_RT288X [=n] The reason is that DMA_RALINK selects DMA_ENGINE and DMA_VIRTUAL_CHANNELS without depending on or selecting DMADEVICES while DMA_ENGINE and DMA_VIRTUAL_CHANNELS are subordinate to DMADEVICES. This can also fail building the kernel as demonstrated in a bug report. Honor the kconfig dependency to remove unmet direct dependency warnings and avoid any potential build failures.

Fix this by cleaning up driver's VXLAN database in the nic unload flow, before firmware tear-down.

async_icosq_lock may be taken from softirq and non-softirq contexts. It requires protection with spin_lock_bh, otherwise a softirq may be triggered in the middle of the critical section, and it may deadlock if it tries to take the same lock.

2020-11-05net/mlx5e: Protect encap route dev from concurrent releaseVlad Buslov3-28/+52
In functions mlx5e_route_lookup_ipv{4|6}() route_dev can be arbitrary net device and not necessary mlx5 eswitch port representor. As such, in order to ensure that route_dev is not destroyed concurrent the code needs either explicitly take reference to the device before releasing reference to rtable instance or ensure that caller holds rtnl lock. First approach is chosen as a fix since rtnl lock dependency was intentionally removed from mlx5 TC layer. To prevent unprotected usage of route_dev in encap code take a reference to the device before releasing rt. Don't save direct pointer to the device in mlx5_encap_entry structure and use ifindex instead. Modify users of route_dev pointer to properly obtain the net device instance from its ifindex.

2020-11-05media: mtk-vcodec: fix build breakage when one of VPU or SCP is enabledAlexandre Courbot3-9/+47
The addition of MT8183 support added a dependency on the SCP remoteproc module. However the initial patch used the "select" Kconfig directive, which may result in the SCP module to not be compiled if remoteproc was disabled. In such a case, mtk-vcodec would try to link against non-existent SCP symbols. "select" was clearly misused here as explained in kconfig-language.txt. Replace this by a "depends" directive on at least one of the VPU and SCP modules, to allow the driver to be compiled as long as one of these is enabled, and adapt the code to support this new scenario. Also adapt the Kconfig text to explain the extra requirements for MT8173 and MT8183.

Some calls in the debugfs interface are made to the linux/uaccess.h header, but the header is not referenced. So, for x86_64 architectures, this dependency seems to be pulled in elsewhere, which leads to a successful compilation. However, on arm/arm64 architectures, it was found to error out on implicit declarations. This change fixes the implicit declaration error by adding the linux/uaccess.h header.

It appears that simplification of mcp23s08_spi_regmap_init() made a regression due to wrong size calculation for dev_kmemdup() call.

2020-11-05HID: mcp2221: Fix GPIO output handlingLars Povlsen1-9/+39
The mcp2221 driver GPIO output handling has has several issues. * A wrong value is used for the GPIO direction. * Wrong offsets are calculated for some GPIO set value/set direction operations, when offset is larger than 0. This has been fixed by introducing proper manifest constants for the direction encoding, and using 'offsetof' when calculating GPIO register offsets. The updated driver has been tested with the Sparx5 pcb134/pcb135 board, which has the mcp2221 device with several (output) GPIO's.

Use the uic_cmd->cmd_active as a flag to track the lifecycle of an UIC cmd. The flag is set before sending the UIC cmd and cleared in IRQ handler. When a PMC or UIC cmd completion timeout happens, if the flag is not set, instead of returning timeout error, we still treat it as a successful operation. This is to deal with the scenario in which completion has been raised but the one waiting for the completion cannot be awaken in time due to kernel scheduling problem.

However, if specific ufshcd_hold/release sequences are met, it is possible that scsi_block_reqs_cnt is increased twice but only one ungate work is queued. To make sure scsi_block_reqs_cnt is handled by ufshcd_hold() and ufshcd_ungate_work() in a paired way, increase it only if queue_work() returns true.

2020-11-04PCI: mvebu: Fix duplicate resource requestsRob Herring1-13/+10
With commit 669cbc708122 ("PCI: Move DT resource setup into devm_pci_alloc_host_bridge()"), the DT 'ranges' is parsed and populated into resources when the host bridge is allocated. The resources are requested as well, but that happens a second time for the mvebu driver in mvebu_pcie_parse_request_resources(). We should only be requesting the additional resources added in mvebu_pcie_parse_request_resources(). These are not added by default because they use custom properties rather than standard DT address translation. Also, the bus ranges was also populated by default, so we can remove it from mvebu_pci_host_probe().

Prior to commit 0f71c60ffd26 ("PCI: dwc: Remove storing of PCI resources"), the DWC driver was setting up the last memory resource rather than the first memory resource. This doesn't matter for most platforms which only have 1 memory resource, but it broke Tegra194 which has a 2nd (prefetchable) memory region that requires an ATU entry. The first region on Tegra194 relies on the default 1:1 pass-thru of outbound transactions and doesn't need an ATU entry.
