Subject: [PATCH 4/7] i2c: pxa: remove some unnecessary debug
|

|
Remove unnecessary show_state() in the loop inside
|
|
i2c_pxa_pio_set_master(), which can be unnecessarily verbose.
|
|
|
|
Remove the i2c_pxa_scream_blue_murder() in i2c_pxa_pio_xfer(), which
|
|
will trigger if we are probing the I2C bus and a slave does not
|
|
respond; this is a normal event, and not something to report.
