From 41c4e35037337cfcd297322f3f60770955156683 Mon Sep 17 00:00:00 2001 From: Shinya Kuribayashi Date: Fri, 6 Nov 2009 21:50:22 +0900 Subject: i2c-designware: i2c_dw_read: Remove redundant target address checker I2c_dw_xfer_msg() also has the same target address inconsistency check, and furthermore it checks across all i2c_msg messages, while i2c_dw_read() walks through i2c_msg messages only with_ I2C_M_RD flag. That is, target address check in i2c_dw_read() is redundant and useless.
