Frank Li fe52ab31f0 i3c: add actual_len in i3c_priv_xfer ... [ Upstream commit e5e3df06ac ] In MIPI I3C Specification: "Ninth Bit of SDR Target Returned (Read) Data as End-of-Data: In I2C, the ninth Data bit from Target to Controller is an ACK by the Controller. By contrast, in I3C this bit allows the Target to end a Read, and allows the Controller to Abort a Read. In SDR terms, the ninth bit of Read data is referred to as the T-Bit (for ‘Transition’)" I3C allow devices early terminate data transfer. So need "actual_len" field to indicate how much get by i3c_priv_xfer.
