From bc15cde0c4acc9128f26ff78f99ce34a59200d5e Mon Sep 17 00:00:00 2001 From: Corey Minyard Date: Tue, 20 Nov 2018 11:13:42 -0600 Subject: i2c: Don't check return value from i2c_recv() i2c_recv() cannot fail, so there is no need to check the return value. It also returns unt8_t, so comparing with < 0 is not meaningful. Fix up various I2C controllers to remove the unneeded code.
