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.

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.

The problem is we had a request in the queue at the same time, so we completed the request twice. This can actually happen in a lot of cases, we fail to get a ref on our config, we only have one connection and just error out the command, etc. Fix this by checking cmd->status in nbd_read_stat. We only change this under the cmd->lock, so we are safe to check this here and see if we've already error'ed this command out, which would indicate that we've completed it as well.

We already do this for the most part, except in timeout and clear_req. 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. For the clear_req cause this is initiated by the user, so again is safe.

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.

Pull power management fixes from Rafael Wysocki: "These fix problems related to frequency limits management in cpufreq that were introduced during the 5.3 cycle (when PM QoS had started to be used for that), fix a few issues in the OPP (operating performance points) library code and fix up the recently added haltpoll cpuidle driver. The cpufreq changes are somewhat bigger that I would like them to be at this stage of the cycle, but the problems fixed by them include crashes on boot and shutdown in some cases (among other things) and in my view it is better to address the root of the issue right away. Specifics: - Using device PM QoS of CPU devices for managing frequency limits in cpufreq does not work, so introduce frequency QoS (based on the original low-level PM QoS) for this purpose, switch cpufreq and related code over to using it and fix a race involving deferred updates of frequency limits on top of that (Rafael Wysocki, Sudeep Holla). - Avoid calling regulator_enable()/disable() from the OPP framework to avoid side-effects on boot-enabled regulators that may change their initial voltage due to performing initial voltage balancing without all restrictions from the consumers (Marek Szyprowski). - Avoid a kref management issue in the OPP library code and drop an incorrectly added lockdep_assert_held() from it (Viresh Kumar). - Make the recently added haltpoll cpuidle driver take the 'idle=' override into account as appropriate (Zhenzhong Duan)" * tag 'pm-5.4-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: opp: Reinitialize the list_kref before adding the static OPPs again cpufreq: Cancel policy update work scheduled before freeing cpuidle: haltpoll: Take 'idle=' override into account opp: core: Revert "add regulators enable and disable" PM: QoS: Drop frequency QoS types from device PM QoS cpufreq: Use per-policy frequency QoS PM: QoS: Introduce frequency QoS opp: of: drop incorrect lockdep_assert_held()

When in slave mode, an arbitration loss (ARLO) may be detected before the slave had a chance to detect the stop condition (STOPF in ISR). This is seen when two master + slave adapters switch their roles. It provokes the i2c bus to be stuck, busy as SCL line is stretched. - the I2C_SLAVE_STOP event is never generated due to STOPF flag is set but don't generate an irq (race with ARLO irq, STOPIE is masked). STOPF flag remains set until next master xfer (e.g. when STOPIE irq get unmasked). In this case, completion is generated too early: immediately upon new transfer request (then it doesn't send all data). - Some data get stuck in TXDR register. As a consequence, the controller stretches the SCL line: the bus gets busy until a future master transfer triggers the bus busy / recovery mechanism (this can take time... and may never happen at all) So choice is to let the STOPF being detected by the slave isr handler, to properly handle this stop condition. E.g. don't mask IRQs in error handler, when the slave is running.
