[PATCH] au1100fb: Add option to enable/disable the cursor
- add cursor enable/disable, very useful if you wish a full screen boot
logo.
Cursor can be disabled from kernel command line:
video=au1100fb:nocursor,panel:Toppoly_TD035STED4
or from sysfs interface:
echo 1 > /sys/module/au1100fb/parameters/nocursor
- fix up some wrong indentation issues.
