[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.
