[Qemu-devel] [PATCH v2 3/3] hw/i386/pc: don't carry FDC from pc_basic_device_init() to pc_cmos_init()

[Laszlo Ersek <lersek@redhat.com>]

Thanks to the last patch, pc_cmos_init() doesn't need the (optional)
board-default FDC any longer as an input parameter. Update
pc_basic_device_init() not to hand it back to pc_init1() / pc_q35_init(),
and update the latter not to carry the FDC to pc_cmos_init(). This
simplifies the code.

pc_init1() | pc_q35_init()
  pc_basic_device_init()
  pc_cmos_init()
