A few drivers call fb_find_mode() even if compiled as a module. If the
modedb parameter is NULL, the function will use default modedb array
which is marked __init. This will cause a crash. To avoid this, check if
the driver is compiled as a module, and if it is, fail.
Why limit the default mode DB to built-in drivers only?
The default db is used by drivers only once. After that, it just consumes
memory.
For modules it wouldn't be that hard to add the modedb from userland after
loading. First insmod your module. Normally modular fbdev driver don't set
the hardware explictly. Once we have sysfs it will be easy. Next send the
new modes to the db. Next select the mode you want.
