i2c: core: Fix double-free of fwnode in i2c_unregister_device() (2025-07-28 10:41:36 +0200)
----------------------------------------------------------------
i2c-for-6.17-rc1
I2C Core:
- prevent double-free of an fwnode if it is a software node
- use recent helpers instead of custom ACPI or outdated OF ones
- add a more elaborate description of a message flag
I2C Host drivers, part 1:
Cleanups and refactorings:
- lpi2c, riic, st, stm32f7: general improvements
- riic: support more flexible IRQ configurations
- tegra: fix documentation
Improvements:
- lpi2c: improve register polling and add atomic transfer
- imx: use guarded spinlocks
New hardware support:
- Samsung Exynos 2200
- Renesas RZ/T2H (R9A09G077), RZ/N2H (R9A09G087)
DT binding:
- rk3x: enable power domains
- nxp: support clock property
