Using an unsigned integer to hold the signed return code
is wrong. So fix it by using the correct type to hold the
return code.

msm: camera: Reset CCI core based on I2C MASTER

CCI core is used by camera sensor, actuator and EEPROM. CCI core gets
reset first time when either one of hardware modules initializes it.
But, as per hardware requirement sensor has to be powered up before
CCI can be reset. This imposes limitation in the sequence in which
camera is opened. To remove this limitation, initialize CCI core
only for corresponding I2C MASTER everytime either of the hardware
modules initilizes it.

ASoC: msm-hdmi-codec-rx: sync state with HDMI core

To keep the state of the HDMI core and HDMI audio
sessions congruent, audio checks the state of the
core on startup, then notifies the core of the
active audio session.  On shutdown, notifies the
core of the event.

video: slimport: wait until boot done before start detection

If slimport cable inserted during boot up, slimport could not
work properly since other system is not ready yet. So, wait
until boot completion before start cable detection. The boot
completion should be notified by userspace.
