Stefan Wahren e65a9e480e net: qca_spi: Fix race condition in spi transfers ... With performance optimization the spi transfer and messages of basic register operations like qcaspi_read_register moved into the private driver structure. But they weren't protected against mutual access (e.g. between driver kthread and ethtool). So dumping the QCA7000 registers via ethtool during network traffic could make spi_sync hang forever, because the completion in spi_message is overwritten. So revert the optimization completely.
