Subject: [PATCH 5/9] mfd: lp87565: Fix Wvoid-pointer-to-enum-cast warning

'dev_type' is an enum, thus cast of pointer on 64-bit compile test with
W=1 causes:

  lp87565.c:95:23: error: cast to smaller integer type 'enum lp87565_device_type' from 'const void *' [-Werror,-Wvoid-pointer-to-enum-cast]
