[PATCH 3.16 061/233] serial: ifx6x60: Remove dangerous spi_driver casts

[Ben Hutchings]

3.16.48-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Geert Uytterhoeven <geert@xxxxxxxxxxxxxx>

commit 9a499db0325b8a8e2368f21fef66705b120f38ba upstream.

Casting spi_driver pointers to "void *" when calling
spi_{,un}register_driver() bypasses all type checking.

Remove the superfluous casts to fix this.
