- Improvements & Fixes
   - Qualcomm WLED: Fix a NULL pointer dereference in `wled_remove()` by setting platform
     driver data in `wled_probe()`
   - Qualcomm WLED: Fix the WLED3 brightness register stride to prevent consecutive string
     writes from overlapping
   - Qualcomm WLED: Read back the hardware-programmed brightness at probe, expose it via
     `get_brightness()`, and prevent unbalanced OVP IRQ enabling
   - TI LM3630A: Cancel delayed work synchronously after freeing the IRQ and before
     destroying the workqueue in `lm3630a_remove()`
