a19a6ee6ca backlight: Allow properties to be passed at registration
Values such as max_brightness should be set before backlights are
registered, but the current API doesn't allow that. Add a parameter to
backlight_device_register and update drivers to ensure that they
set this correctly.

a4ebb780e1 video: backlight/progear, fix pci device refcounting
Stanse found an ommitted pci_dev_puts on error path in progearbl_probe.
pmu_dev and sb_dev are gotten, but never put when
backlight_device_register fails.

So unify fail paths and put the devs when the failure occurs.

6cd6f35a4b backlight: progear_bl - Use platform_device_register_simple()
Use platform_device_register_simple() and also fix error
handling when platform_device_alloc() fails (progearbl_driver
is left registered).

84902b7af6 fbdev: change asm/uaccess.h to linux/uaccess.h
This patch replaces <asm/uaccess.h> with <linux/uaccess.h> after the
checkpatch.pl hint.  The include of <asm/uaccess.h> is removed if the driver
does not use it.

599a52d126 backlight: Separate backlight properties from backlight ops pointers
Per device data such as brightness belongs to the indivdual device
and should therefore be separate from the the backlight operation
function pointers. This patch splits the two types of data and
allows simplifcation of some code.

dfcba20067 backlight: Remove unneeded owner field
Remove uneeded owner field from backlight_properties structure.

Nothing uses it and it is unlikely that it will ever be used. The
backlight class uses other means to ensure that nothing references
unloaded code.

Based on a patch from Dmitry Torokhov <dtor@insightbb.com>
