Greg Kroah-Hartman 2712a7d362 spi: gpio: fix const issue in spi_to_spi_gpio() ...

While the struct spi_device * passed into spi_to_spi_gpio() is a const
one, the struct spi_bitbang * that is retrieved from the controller
field in the spi_device is NOT a const pointer, as it is coming from the
spi_controller_get_devdata() call, and then passed to container_of()
which would strip off the const attribute for no good reason (i.e. if a
const pointer is passed to container_of() it still is const coming out).

Fix this all up by properly declaring the struct spi_bitbang * as not
const.
