From aea31bf35f569aca4ec2091d7050488c0182926a Mon Sep 17 00:00:00 2001 From: Antony Pavlov Date: Tue, 17 Apr 2018 06:58:29 +0300 Subject: commands: i2c_write: enable reg == 0 too This commit fixes the mistake introduced in the commit 34fadb685905 ('commands: i2c_write: enable raw write to address'). The intended behaviour for i2c_write command is "use raw i2c write only if reg address is not defined". Before the commit 34fadb685905 reg address == 0 was acceptable. After the commit 34fadb685905 reg address == 0 became unacceptable ("undefined") and will lead to raw i2c write.
