Merge tag 'i2c-host-fixes-6.8-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-mergewindow

This tag includes two fixes. The first one, in the Cadence driver
seen in Qemu, prevents unintentional FIFO clearing at the
beginning of a transaction. The second fix, in the SynQuacer,
ensures proper error handling during clock get, prepare, and
enable operations by using the devm_clk_get_enabled() helper.
