User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/40.0.2214.94 Safari/537.36

Steps to reproduce:

Build using:

BRANCH=v1.3t ./config.sh tarako
./build.sh

Flash kernel after rebuilding boot.img. Reboot phone

Additional Info (from phone factory firmware):

Model: U105 FIRE
Software: Boot2Gecko 1.3.0.0-prerelease
Build Identifier: 20141119163335
Git commit info: 1556da1f



Actual results:

From the factory kernel, I can see the following in dmesg:


kernel build from source shows:
$ adb shell
# dmesg

Expected results:

factory kernel shows:

$adb shell
# dmesg

<6>0[    0.072610] sprdfb:[sprdfb_probe]
<6>0[    0.072715] LCD Panel 0x99 is attached

There is not driver in kernel sources with LCD id 0x99.
