Subject: [PATH backport 1/2] mlxsw: i2c: Limit single transaction buffer size
|
|
|
|
Maximum size of buffer is obtained from underlying I2C adapter and in
|
|
case adapter allows I2C transaction buffer size greater than 100 bytes,
|
|
transaction will fail due to firmware limitation.
|
|
Limit the maximum size of transaction buffer by 100 bytes to fit to
|
|
firmware.
|
|
|
|
Fixes: 3029a693beda ("mlxsw: i2c: Allow flexible setting of I2C transactions size")
