[PATCH 1/4] spi: spi-bitbang: change flags from u8 to u16

2018-07-16 Thread David Lechner 
This changes the data type of the flags field in struct spi_bitbang from
u8 to u16. This matches the size of the mode field of struct spi_device
where these flags are also used.

This is done in preparation of adding a new SPI mode flag that will be
used with this field that would otherwise not fit in 8 bits.
