From: Shailendra Verma <shailendra.v@xxxxxxxxxxx>
In this function "fb_create_modedb" the memory for video mode is getting
allocated before the edid validation.If the validation of edid fails
then we are freeing the allocated memory for the video mode and returning.
So moving the memory allocation part after the edid validation.There is no
need to allocate the memory before edid validation check and freeing if
validation gets failed.
