Other edits consist in: - Improving formatting for flag values for "bpf_fib_lookup()" helper. - Emphasising a parameter name in description of the return value for "bpf_get_stack()" helper. - Removing unnecessary blank lines between "Description" and "Return" sections for the few helpers that would use it, for consistency.

2018-05-29block: remove parent device reference from struct bsg_class_deviceChristoph Hellwig
Bsg holding a reference to the parent device may result in a crash if a bsg file handle is closed after the parent device driver has unloaded. Holding a reference is not really needed: the parent device must exist between bsg_register_queue and bsg_unregister_queue. Before the device goes away the caller does blk_cleanup_queue so that all in-flight requests to the device are gone and all new requests cannot pass beyond the queue. The queue itself is a refcounted object and it will stay alive with a bsg file. Based on analysis, previous patch and changelog from Anatoliy Glagolev.

2018-05-29IB/core: Fix error code for invalid GID entryParav Pandit
When a GID entry is invalid EAGAIN is returned. This is an incorrect error code, there is nothing that will make this GID entry valid again in bounded time. Some user space tools fail incorrectly if EAGAIN is returned here, and this represents a small ABI change from earlier kernels. The first patch in the Fixes list makes entries that were valid before to become invalid, allowing this code to trigger, while the second patch in the Fixes list introduced the wrong EAGAIN. Therefore revert the return result to EINVAL which matches the historical expectations of the ibv_query_gid_type() API of the libibverbs user space library.

2018-05-29i2c: qup: Correct duty cycle for FM and FM+Austin Christ
The I2C spec UM10204 Rev. 6 specifies the following timings. Standard Fast Mode Fast Mode Plus SCL low 4.7us 1.3us 0.5us SCL high 4.0us 0.6us 0.26us This results in a 33%/66% duty cycle as opposed to the 50%/50% duty cycle used for Standard-mode. Add High Time Divider settings to correct duty cycle for FM(400kHz) and FM+(1MHz).
