The patch looks OK to me, but can you please trim down the warning for
prettier git log output? At least the timestamps can go, and since
you fixed it, you could trim the message down to something like this:

serial8250 serial8250.1: incomplete constraints, dummy supplies not allowed
WARNING: CPU: 0 PID: 1 at drivers/base/core.c:2486 device_release+0x98/0xa8
Device 'serial8250.1' does not have a release() function, it is broken and
must be fixed. See Documentation/core-api/kobject.rst.

ams_delta_init_late from init_machine_late+0x1c/0x94
init_machine_late from do_one_initcall+0x60/0x1d4

This still allows folks seeing similar errors to find them when searching.
Also the ASoC warnings can be trimmed down a bit, formatting up to you
how you prefer them naturally :)

Thanks,

Tony
