X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dbd4f12859307c20a4c65a7de4cdd5f9f518dc7a;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git [PATCH] fbcon: don't repaint the cursor when it is disabled. Currently even when the cursor is disabled (`setterm -cursor off`), it is still repainted as a black rectangle the size of a single char. This can be seen, for example, by chvt'ing to a free tty, disabling the cursor and doing `dd if=3D/dev/urandom of=3D/dev/fb0`. The patch changes this behaviour by avoiding painting anything when the cursor is disabled.
