[PATCHv2 2/7] rtc: Convert struct i2c_msg initialization to C99 format

From: Shubhrajyoti D
Date: Mon Sep 24 2012 - 05:48:52 EST


Convert the struct i2c_msg initialization to C99 format. This makes
maintaining and editing the code simpler. Also helps once other fields
like transferred are added in future.
