The I2C adapter driver is sometimes slow, causing the SCL line to be stuck low for more than the stipulated SMBUS timeout of 25-35 ms. This causes the client device to give up which in turn causes silent corruption of data. So, disable the SMBUS timeout in the client device. Signed-off-by: Peter Rosin <redacted>
Acked-by: Guenter Roeck <linux@roeck-us.net> I assume this will be sent upstream through an arm tree. Thanks, Guenter
