A read failure fell straight back into open_imu: a chip that answers its ID but cannot stream was reopened in a tight loop, warning each time, on the bus the audio codec shares. Same backoff as the open-failure path, which the module docs always claimed.

A read failure in the BMI088 loop fell straight back into
open_imu: a chip that answers its ID but cannot stream was reopened in a tight loop, warning each time, on the I²C bus the audio codec shares. The open-failure path has always backed off; the read-failure path now waits on the same backoff, which is what the module docs already claimed.No new arithmetic — the retry sequence is the one the open-failure path and the ToF loop already use — so no new unit test; the loop itself needs the chip.
