Subject: [PATCH 1/3] [POWERPC] fsl_soc: fix uninitialized i2c_board_info structure

From: Anton Vorontsov <[email-masked]>
Date: Tue, 2 Oct 2007 17:47:40 +0400

i2c_board_info used semi-initialized, causing garbage in the
info->flags, and that, in turn, causes various symptoms of i2c
malfunctioning, like PEC mismatches.
