From 2ac4c5f4d2415116d3f417a32311d437791dcfce Mon Sep 17 00:00:00 2001 From: Corey Minyard Date: Wed, 14 Nov 2018 11:50:50 -0600 Subject: i2c: have I2C receive operation return uint8_t MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit It is never supposed to fail and cannot return an error, so just have it return the proper type. Have it return 0xff on nothing available, since that's what would happen on a real bus.
