Subject: Re: [PATCH v3 3/4] fbdev: omapfb: Make FB_DEVICE dependency optional

* Chintan Patel <chintanlike@...il.com>:
> omapfb provides several sysfs interfaces for framebuffer configuration
> and debugging, but these are not required for the core driver.
> 
> Remove the hard dependency on CONFIG_FB_DEVICE and make sysfs support
> optional by using dev_of_fbinfo() to obtain the backing device at runtime.
> When FB_DEVICE is disabled, sysfs operations are skipped while the code
> still builds and is type-checked.
