Use raw-format drives
Hi,
I am currently using a Windows program, that is trying to read a raw-format drive through USB.
I've tried making a symbolic link to the device from my dosdevices directory
ln -s /dev/disk3 x:
but the program still doesn't recognise it.
This program currently works on winxp.
Is there any way to read such a drive through wine?
Thanks,
Anna.

[PATCH v2 0/8] fbdev: Clean up include dependencies in header
Remove unnecessary dependencies in the include statements of the
header file <linux/fb.h>. Several files throughout the kernel include
the fbdev header, so reducing dependencies positively affects other
subsystems as well. Also fix up nouveau and fbtft, which need backlight.h
in some their source files.
v2:
* include backlight.h in fbtft (kernel test robot)
