Subject: [PATCH] mfd: wm8994: fix compile warning in wm8994_i2c_probe()

When building a 64-bit kernel we get following compiler warning:

drivers/mfd/wm8994-core.c: In function ‘wm8994_i2c_probe’:
drivers/mfd/wm8994-core.c:758:19: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]

Fix this by casting the of_id->data to kernel_ulong_t as it should be the
same size than the native pointer type.
