Subject: [PATCH v3 3/3] intel-mid: Move boundry check to the start of init code
Date: Thu,  8 Sep 2016 19:07:10 -0700	[thread overview]
Message-ID: <d1643b61f9d5b6fe7d1b168341d9b1e89696c43b.1473386382.git.sathyanarayanan.kuppuswamy@linux.intel.com> (raw)
In-Reply-To: <1473210255-227672-1-git-send-email-sathyanarayanan.kuppuswamy@linux.intel.com>
In-Reply-To: <ee8b3baa53bd44504b5448a790fb15750f90675b.1473386382.git.sathyanarayanan.kuppuswamy@linux.intel.com>

Moved the instance boundary check to the start of the pcal9555a
platform init code. This will prevent unnecessary initialization
on instance boundary error.
