From 8b57cebedd3e8a384ab678a69e9b7128eb438a1f Mon Sep 17 00:00:00 2001 From: Fan Du Date: Tue, 16 Sep 2014 17:21:03 +0800 Subject: [PATCH] i2c: ismt: Use minimum descriptor size Software is allowed to allocate number of descriptor size from 2 to 256, this i2c controller could process more descriptor, but for i2c core soft ware layer, only one i2c transaction is allowed each time. So here switch to minimum 2 descriptor when initialization.
