I'm sorry for the spaces in the second patch, here's a clean one with tabs.
--- From: Stefan Bauer <stefan.bauer@cs.tu-chemnitz.de>
Since 4c7ffe0b9f7f40bd818fe3af51342f64c483908e ("fbdev: prevent drivers that have hardware cursors from calling software cursor code") every call of i810fb_cursor fails with -ENXIO because of a incorrect "!".
This hasn't striked until eaa0ff15c30dc9799eb4d12660edb73aeb6d32c5 ("fix ! versus & precedence in various places") surrounded the expression with braces, so that the intended behavior was inverted. That caused 'pixel waste' - the same line of multi-colored pixels repeated over the whole screen - during console switch.
This switches back to the original pre-4c7ffe0 behavior.
