mfd: cros ec: spi: Fix "in progress" error signaling For host commands that take a long time to process, cros ec can return early by signaling a EC_RES_IN_PROGRESS result. The host must then poll status with EC_CMD_GET_COMMS_STATUS until completion of the command. None of the above applies when data link errors are encountered. When errors such as EC_SPI_PAST_END are encountered during command transmission, it usually means the command was not received by the EC. Treating such errors as if they were 'EC_RES_IN_PROGRESS' results is almost always the wrong decision, and can result in host commands silently being lost.
