Merge tag 'i2c-host-fixes-6.13-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-current
i2c-host-fixes for v6.13-rc5
- IMX: fixed stop condition in single master mode and added
compatible string for errata adherence.
- Microchip: Added support for proper repeated sends and fixed
unnecessary NAKs on empty messages, which caused false bus
detection.
