2019-10-26staging: rtl8188eu: reduce indentation level in rtw_alloc_stainfoMichael Straube
Remove else-arm from if-else statement. Move the else code out of the if-else and skip it by adding goto exit to the if block. The exit label was directly after the else-arm, so there is no change in behaviour. Reduces indentation level and clears a line over 80 characters checkpatch warning.

2019-10-26staging: wfx: fix CONFIG_MMC=m with CONFIG_WFX=yJérôme Pouiller

This patch disallows CONFIG_WFX=y if CONFIG_MMC=m. This solution impacts users who want to use SPI bus with configuration: CONFIG_WFX=y + CONFIG_SPI=y + CONFIG_MMC=m. However, I think this is a twisted case. So, I think it won't be missed.

2019-10-25nbd: verify socket is supported during setupMike Christie
nbd requires socket families to support the shutdown method so the nbd recv workqueue can be woken up from its sock_recvmsg call. If the socket does not support the callout we will leave recv works running or get hangs later when the device or module is removed. This adds a check during socket connection/reconnection to make sure the socket being passed in supports the needed callout.

2019-10-25ata: libahci_platform: Fix regulator_get_optional() misuseMark Brown
This driver is using regulator_get_optional() to handle all the supplies that it handles, and only ever enables and disables all supplies en masse without ever doing any other configuration of the device to handle missing power. These are clear signs that the API is being misused - it should only be used for supplies that may be physically absent from the system and in these cases the hardware usually needs different configuration if the supply is missing. Instead use normal regualtor_get(), if the supply is not described in DT then the framework will substitute a dummy regulator in so no special handling is needed by the consumer driver. In the case of the PHY regulator the handling in the driver is a hack to deal with integrated PHYs; the supplies are only optional in the sense that that there's some confusion in the code about where they're bound to. From a code point of view they function exactly as normal supplies so can be treated as such. It'd probably be better to model this by instantiating a PHY object for integrated PHYs.

For the timeout case we take the lock after we grab a ref on the config, but that isn't really necessary because we're safe to touch the cmd at this point, so just move the order around.

2019-10-25io_uring: fix bad inflight accounting for SETUP_IOPOLL|SETUP_SQTHREADJens Axboe
We currently assume that submissions from the sqthread are successful, and if IO polling is enabled, we use that value for knowing how many completions to look for. But if we overflowed the CQ ring or some requests simply got errored and already completed, they won't be available for polling. For the case of IO polling and SQTHREAD usage, look at the pending poll list. If it ever hits empty then we know that we don't have anymore pollable requests inflight. For that case, simply reset the inflight count to zero.

2019-10-25io_uring: used cached copies of sq->dropped and cq->overflowJens Axboe
We currently use the ring values directly, but that can lead to issues if the application is malicious and changes these values on our behalf. Created in-kernel cached versions of them, and just overwrite the user side when we update them. This is similar to how we treat the sq/cq ring tail/head updates.

2019-10-25io_uring: Fix broken links with offloadingPavel Begunkov
io_sq_thread() processes sqes by 8 without considering links. As a result, links will be randomely subdivided. The easiest way to fix it is to call io_get_sqring() inside io_submit_sqes() as do io_ring_submit(). Downsides: 1. This removes optimisation of not grabbing mm_struct for fixed files 2. It submitting all sqes in one go, without finer-grained sheduling with cq processing. Signed-off-by: Pavel Begunkov <asml.silence@gmail.com> Signed-off-by: Jens Axboe <axboe@kernel.dk>
2019-10-25io_uring: Fix corrupted user_dataPavel Begunkov
There is a bug, where failed linked requests are returned not with specified @user_data, but with garbage from a kernel stack. The reason is that io_fail_links() uses req->user_data, which is uninitialised when called from io_queue_sqe() on fail path.

2019-10-25irqchip/sifive-plic: Skip contexts except supervisor in plic_init()Alan Mikhak
Modify plic_init() to skip .dts interrupt contexts other than supervisor external interrupt. The .dts entry for plic may specify multiple interrupt contexts. For example, it may assign two entries IRQ_M_EXT and IRQ_S_EXT, in that order, to the same interrupt controller. This patch modifies plic_init() to skip the IRQ_M_EXT context since IRQ_S_EXT is currently the only supported context. If IRQ_M_EXT is not skipped, plic_init() will report "handler already present for context" when it comes across the IRQ_S_EXT context in the next iteration of its loop. Without this patch, .dts would have to be edited to replace the value of IRQ_M_EXT with -1 for it to be skipped.
