[PATCH 00/21] leds: Assorted bug fixes across core, flash, trigger, and drivers

[Lee Jones]

These issues were reported by Sashiko.

This series addresses a collection of bugs across the LEDs subsystem,
including locking and concurrency fixes, device-tree node reference
leaks, out-of-bounds array accesses, divide-by-zero and current-limit
clamping issues, and devres lifecycle ordering fixes.
