2019-10-29Input: kxtj9 - switch to using polled mode of input devicesDmitry Torokhov2-122/+37
We have added polled mode to the normal input devices with the intent of retiring input_polled_dev. This converts kxtj9 driver to use the polling mode of standard input devices and removes dependency on INPUT_POLLDEV. note that with regular input devices handling polling, there is no longer a benefit in having separate INPUT_KXTJ9_POLLED_MODE config option.

2019-10-25ata: libahci_platform: Fix regulator_get_optional() misuseMark Brown1-24/+14
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.

2019-10-25io_uring: fix bad inflight accounting for SETUP_IOPOLL|SETUP_SQTHREADJens Axboe1-12/+32
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.
