issue-1 In case combined transfer mode fails halfway, the processing must be stopped halfway. However currently, the processing is continued. This patch breaks the processing.
issue-2 Currently, pch_i2c_xfer returns read/write size at that time. However pch_i2c_xfer must return the number of messages to be read/written. This patch modifies correctly.
