Merge tag 'i2c-host-fixes-6.11-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-current
The Aspeed driver tracks the controller's state (stop, pending, start, etc.). Previously, when the stop command was sent, the state was not updated. The fix in this pull request ensures the driver's state is aligned with the device status. The Intel SCH driver receives a new look, and among the cleanups, there is a fix where, due to an oversight, an if/else statement was missing the else, causing it to move forward instead of exiting the function in case of an error. The Qualcomm GENI I2C driver adds the IRQF_NO_AUTOEN flag to the IRQ setup to prevent unwanted interrupts during probe. The Xilinx XPS controller fixes TX FIFO handling to avoid missed NAKs. Another fix ensures the controller is reinitialized when the bus appears busy.
