2024-05-09ptp: ocp: fix DPLL functionsVadim Fedorenko
In ptp_ocp driver pin actions assume sma_nr starts with 1, but for DPLL subsystem callback 0-based index was used. Fix it providing proper index.

2024-05-09net/sched: adjust device watchdog timer to detect stopped queue at right timePraveen Kumar Kannoju
Applications are sensitive to long network latency, particularly heartbeat monitoring ones. Longer the tx timeout recovery higher the risk with such applications on a production machines. This patch remedies, yet honoring device set tx timeout. Modify watchdog next timeout to be shorter than the device specified. Compute the next timeout be equal to device watchdog timeout less the how long ago queue stop had been done. At next watchdog timeout tx timeout handler is called into if still in stopped state. Either called or not called, restore the watchdog timeout back to device specified.

2024-05-10media: bcm2835-unicam: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

__start_server() sets SO_REUSPORT through setsockopt() when the parameter 'reuseport' is set.

The 'const struct post_socket_opts *cb_opts' args in the post_socket_cb is for the future extension. The 'reuseport' parameter can be dropped. Now the original start_reuseport_server() can be implemented by setting a newly defined reuseport_cb() function pointer to post_socket_cb filed of struct network_helper_opts.

2024-05-09hwmon: Drop explicit initialization of struct i2c_device_id::driver_data to ↵Uwe Kleine-König
0 (part 2) These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. This is a follow up to commit d8a66f3621c2 ("hwmon: Drop explicit initialization of struct i2c_device_id::driver_data to 0") which I created before identifying a few corner cases in my conversion script.
