Do not infinitely retry register readq and writeq operations in order to not lock up the CPU in case the TWSI gets stuck. Return -EIO in case of a failed data read. For all other cases just return so subsequent operations will fail and trigger the recovery. Signed-off-by: Jan Glauber <redacted>
I didn't really check, but have you considered using readq_poll_timeout() from iopoll.h?
