Currently from kobject view, both q->mq_kobj and ctx->kobj can be released during one cycle of blk_mq_register_dev() and blk_mq_unregister_dev(). Actually, sw queue's lifetime is same with its request queue's, which is covered by request_queue->kobj. So we don't need to call kobject_put() for the

This patch removes kobject_put() over hctx in __blk_mq_unregister_dev(), and trys to keep lifetime consistent between hctx and hctx's kobject. Now blk_mq_sysfs_register() and blk_mq_sysfs_unregister() become totally symmetrical, and kobject's refcounter drops to zero just when the hctx is freed.

[PATCH v3 2/4] iio: accel: adxl345: Use I2C regmap instead of direct I2C access

Convert the driver to use regmap instead of I2C-specific functions. Also, introduce the header file "adxl345.h" and export the probe and remove functions. This is done in preparation for splitting this driver into core and I2C-specific code as well as introduction of SPI driver. Signed-off-by:

[PATCH v3 0/4] iio: accel: adxl345: Split driver into core and I2C then add SPI support

This patchset modifies the adxl345 to use regmap. In doing so, we can easily introduce SPI support and let regmap handle the rest. Recap of basic features: read_raw for x, y and z axes, scale. After applying this series, driver now supports the SPI protocol and enumeration of device via device
