From: Arnd Bergmann <arnd@arndb.de>

commit 11ca605653480b2ddc70ec142a0a686796a7fc87 upstream.

The previous bugfix caused a warning on 64-bit builds:

drivers/input/touchscreen/ads7846.c:1126:17: warning: cast to smaller integer type 'u32' (aka 'unsigned int') from 'const void *' [-Wvoid-pointer-to-int-cast]

Change the cast back to something that works on both 32-bit and 64-bit
kernels.
