+Subject: [PATCH 4/7] i2c: pxa: remove some unnecessary debug
+MIME-Version: 1.0
+Content-Disposition: inline
+Content-Transfer-Encoding: 8bit
+Content-Type: text/plain; charset="utf-8"
+
+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.
+
