Merge tag 'i2c-host-fixes-6.11-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-current
Two fixes on the Qualcomm GENI I2C controller are cleaning up the
error exit patch in the runtime_resume() function. The first is
disabling the clock, the second disables the icc on the way out.
