   3 Subject: [PATCH 4/7] i2c: pxa: remove some unnecessary debug
   4 MIME-Version: 1.0
   5 Content-Disposition: inline
   6 Content-Transfer-Encoding: 8bit
   7 Content-Type: text/plain; charset="utf-8"
   8
   9 Remove unnecessary show_state() in the loop inside
  10 i2c_pxa_pio_set_master(), which can be unnecessarily verbose.
  11
  12 Remove the i2c_pxa_scream_blue_murder() in i2c_pxa_pio_xfer(), which
  13 will trigger if we are probing the I2C bus and a slave does not
  14 respond; this is a normal event, and not something to report.
