Subject: spi: spi_s3c24xx must initialize num_chipselect
From: Ben Dooks <ben-linux@xxxxxxxxx>
The s3c24xx_spi_txrx() function should initialise the completion each time
before using it, otherwise we end up with the possibility of returning success
before the interrupt handler has processed all the data.
