| H A D | vga_switcheroo.c | a67b8887 Sun May 15 09:32:50 CDT 2011 Florian Mickler <florian@mickler.org> vga_switcheroo: don't toggle-switch devices
If the requested device is already active, ignore the request.
This restores the original behaviour of the interface. The change was
probably an unintended side effect of
commit 66b37c6777c4 vga_switcheroo: split switching into two stages
which did not take into account to duplicate the !active check in the split-off
stage2.
Fix this by factoring that check out of stage1 into the debugfs_write routine.
