2020-09-23hwmon: use simple i2c probe functionStephen Kitt
Many hwmon drivers don't use the id information provided by the old i2c probe function, and the remainder can easily be adapted to the new form ("probe_new") by calling i2c_match_id explicitly. This avoids scanning the identifier tables during probes. Drivers which didn't use the id are converted as-is; drivers which did are modified as follows: * if the information in i2c_client is sufficient, that's used instead (client->name); * anything else is handled by calling i2c_match_id() with the same level of error-handling (if any) as before. A few drivers aren't included in this patch because they have a different set of maintainers. They will be covered by other patches.

2020-09-23hwmon (pmbus) use simple i2c probe functionStephen Kitt
pmbus_do_probe doesn't use the id information provided in its second argument, so this can be removed, which then allows using the single-parameter i2c probe function ("probe_new") for probes. This avoids scanning the identifier tables during probes. Drivers which didn't use the id are converted as-is; drivers which did are modified as follows: * if the information in i2c_client is sufficient, that's used instead (client->name); * configured v. probed comparisons are performed by comparing the configured name to the detected name, instead of the ids; this involves strcmp but is still cheaper than comparing all the device names when scanning the tables; * anything else is handled by calling i2c_match_id() with the same level of error-handling (if any) as before. Additionally, the mismatch message in the ltc2978 driver is adjusted so that it no longer assumes that the driver_data is an index into ltc2978_id.

2020-09-23hwmon: (sparx5) Fix initial reading of temperatureLars Povlsen
If the temperature is read before the internal calibration is completed, the driver returns -EIO. Instead it should return -EAGAIN to encourage repeating the operation. Note (groeck): Returning -EAGAIN to userspace may result in hard loops; some userspace code interprets -EAGAIN as request to retry immediately. I would prefer -ENODATA, but it turns out that the thermal subsystem only handles -EAGAIN silently, so we'll have to stick with that.

2020-09-23block: allow 'chunk_sectors' to be non-power-of-2Mike Snitzer
It is possible, albeit more unlikely, for a block device to have a non power-of-2 for chunk_sectors (e.g. 10+2 RAID6 with 128K chunk_sectors, which results in a full-stripe size of 1280K. This causes the RAID6's io_opt to be advertised as 1280K, and a stacked device _could_ then be made to use a blocksize, aka chunk_sectors, that matches non power-of-2 io_opt of underlying RAID6 -- resulting in stacked device's chunk_sectors being a non power-of-2). Update blk_queue_chunk_sectors() and blk_max_size_offset() to accommodate drivers that need a non power-of-2 chunk_sectors. Reviewed-by: Ming Lei <ming.lei@redhat.com> Reviewed-by: Martin K.

2020-09-23block: use lcm_not_zero() when stacking chunk_sectorsMike Snitzer
Like 'io_opt', blk_stack_limits() should stack 'chunk_sectors' using lcm_not_zero() rather than min_not_zero() -- otherwise the final 'chunk_sectors' could result in sub-optimal alignment of IO to component devices in the IO stack. Also, if 'chunk_sectors' isn't a multiple of 'physical_block_size' then it is a bug in the driver and the device should be flagged as 'misaligned'.

2020-09-22scsi: qla2xxx: Add SLER and PI control supportSaurav Kashyap
BIT_13 of extended FW attribute informs about NVMe-2 support. Set BIT_15 of special feature control block for enabling SLER in FW. Set bit 8 (SLER supported) to 1 for the service parameter information when sending NVMe PRLI request. Set BIT_14 of special feature control block for enabling PI Control in FW. Driver should set bit 9 (PI Control supported) to 1 for the service parameter information when sending NVMe PRLI request. Set BIT_13 for NVMe Async events.

2020-09-22scsi: qla2xxx: Add IOCB resource trackingQuinn Tran
This patch tracks number of IOCB resources used in the I/O fast path. If the number of used IOCBs reach a high water limit, driver would return the I/O as busy and let upper layer retry. This prevents over subscription of IOCB resources where any future error recovery command is unable to cut through. Enable IOCB throttling by default.
