The v6.12.117 kernel I tested with is not plain stable. It carries a backport of commit 5f5c2d4579ca ("i2c: imx: prevent rescheduling in non dma mode"), so its i2c-imx.c has the interrupt state machine of mainline. "The touched code is the same" is true for that tree only. For stable: both patches apply to 6.18.y and 7.3.y. On 6.12.y and older patch 1 applies with fuzz and patch 2 does not apply, as the interrupt handler is different there. I can send backports for those trees once the patches are in mainline.
