* [PATCH v2] dts: type hints updated for method arguments and return types
@ 2025-08-06 16:29 Andrew Bailey
0 siblings, 0 replies; only message in thread
From: Andrew Bailey @ 2025-08-06 16:29 UTC (permalink / raw)
To: luca.vizzarro; +Cc: abailey, dev, dmarx, probb
Mypy does not check functions and methods that are not entirely type
hinted. This prevents full checks, so they have been added where missing.
Full checks revealed typing errors. One was fixed in this patch, while
others were not applied and left not type hinted.
