If dlfb_usb_probe drops to error path then there is only one
kref_init() call and no kref_get(), so second kref_put() leads to
use after free.
The patch removes superfluous kref_put on dlfb_usb_probe error path.
Found by Linux Driver Verification project (linuxtesting.org).

usb_device_id are not supposed to change at runtime. All functions
working with usb_device_id provided by <linux/usb.h> work with
const usb_device_id. So mark the non-const structs as const.

Add const to bin_attribute structures as they are only passed to the
functions sysfs_{remove/create}_bin_file or
device_{remove/create}_bin_file. The corresponding arguments are of
type const, so declare the structures to be const.

Drop log level for blanking from info to debug. Xorg likes to habitually
unblank when already unblanked and this can fill up logs over a long period
of time.

Small minor cleanup.
This patch removes unneeded initializations of variables
in few places in different functions and one empty line.

The vfree() function performs also input parameter validation. Thus the test
around the call is not needed.
This issue was detected by using the Coccinelle software.

Instead of dereference each byte let's use %*ph specifier in the printk()
calls.

The drivers/video directory is a mess. It contains generic video related
files, directories for backlight, console, linux logo, lots of fbdev
device drivers, fbdev framework files.
Make some order into the chaos by creating drivers/video/fbdev
directory, and move all fbdev related files there.
No functionality is changed, although I guess it is possible that some
subtle Makefile build order related issue could be created by this
patch.
