[30/63] fbcon: Bugfix soft cursor detection in Tile Blitting

From: Greg KH
Date: Fri Mar 25 2011 - 20:17:51 EST


2.6.38-stable review patch. If anyone has any objections, please let us know.

------------------

From: Henry Nestler <henry.nestler@xxxxxxxxx>

commit d6244bc0ed0c52a795e6f4dcab3886daf3e74fac upstream.

Use mask 0x10 for "soft cursor" detection on in function tile_cursor.
(Tile Blitting Operation in framebuffer console).

The old mask 0x01 for vc_cursor_type detects CUR_NONE, CUR_LOWER_THIRD
and every second mode value as "software cursor". This hides the cursor
for these modes (cursor.mode = 0). But, only CUR_NONE or "software cursor"
should hide the cursor.
See also 0x10 in functions add_softcursor, bit_cursor and cw_cursor.
