[PATCH] fbdev: prevent drivers that have hardware cursors from calling software cursor code
This patch removes drivers that have hardware cursors from calling the software cursor code. Also if the driver sets a no hardware cursor flag then the driver reports a error it someone attempts to use the cursor. Signed-off-by: James Simmons <jsimmons@infradead.org> Cc: "Antonino A. Daplas" <adaplas@pol.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
