Thomas Zimmermann 17d6499670 Revert "fbcon: don't lose the console font across generic->chip driver switch" ... [ Upstream commit 12d5796d55 ] This reverts commit ae1287865f. Always free the console font when deinitializing the framebuffer console. Subsequent framebuffer consoles will then use the default font. Rely on userspace to load any user-configured font for these consoles. Commit ae1287865f ("fbcon: don't lose the console font across generic->chip driver switch") was introduced to work around losing the font during graphics-device handover. [1][2] It kept a dangling pointer with the font data between loading the two consoles, which is fairly adventurous hack. It also never covered cases when the other consoles, such as VGA text mode, where involved. The problem has meanwhile been solved in userspace. Systemd comes with a udev rule that re-installs the configured font when a console comes up. [3] So the kernel workaround can be removed. This also removes one of the two special cases triggered by setting FBINFO_MISC_FIRMWARE in an fbdev driver. Tested during device handover from efifb and simpledrm to radeon. Udev reloads the configured console font for the new driver's terminal.
