David Brownell 25d5cb4b03 spi: remove some spidev oops-on-rmmod paths ... Somehow the spidev code forgot to include a critical mechanism: when the underlying device is removed (e.g. spi_master rmmod), open file descriptors must be prevented from issuing new I/O requests to that device. On penalty of the oopsing reported by Sebastian Siewior <bigeasy@tglx.de> ... This is a partial fix, adding handshaking between the lower level (SPI messaging) and the file operations using the spi_dev. (It also fixes an issue where reads and writes didn't return the number of bytes sent or received.) There's still a refcounting issue to be addressed (separately).
