If anyone has any objections, please let me know. ------------------ From: Helge Deller [ Upstream commit 8a32aa17c1cd48df1ddaa78e45abcb8c7a2220d6 ] The pointer to the next STI font is actually a signed 32-bit offset. With this change the 64-bit kernel will correctly subract the (signed 32-bit) offset instead of adding a (unsigned 32-bit) offset. It has no effect on 32-bit kernels. This fixes the stifb driver with a 64-bit kernel on qemu.
