2019-02-14	i2c: core-smbus: don't trace smbus_reply data on errors	John Sperbeck	1	-3/+3
	If an smbus transfer fails, there's no guarantee that the output buffer was written. So, avoid trying to show the output buffer when tracing after an error. This was 'mostly harmless', but would trip up kasan checking if left-over cruft in byte 0 is a large length, causing us to read from unwritten memory.

2017-05-31	i2c: break out smbus support into separate file	Wolfram Sang	1	-0/+249
	Break out the exported SMBus functions and the emulation layer into a separate file. This also involved splitting up the tracing header into an I2C and an SMBus part. Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Wolfram Sang <wsa@the-dreams.de>
