Samuel CUELLA 16b71fdf97 i810: fix kernel crash fix when struct fb_var_screeninfo is supplied ... Prevent the kernel from being crashed by a divide-by-zero operation when supplied an incorrectly filled 'struct fb_var_screeninfo' from userland. Previously i810_main.c:1005 (i810_check_params) was using the global 'yres' symbol previously defined at i810_main.c:145 as a module parameter value holder (i810_main.c:2174). If i810fb is compiled-in or if this param doesn't get a default value, this direct usage leads to a divide-by-zero at i810_main.c:1005 (i810_check_params). The patch simply replace the 'yres' global, perhaps undefined symbol usage by a given parameter structure lookup. This problem occurs with directfb, mplayer -vo fbdev, SDL library. It was also reported ( but non solved ) at: http://mail.directfb.org/pipermail/directfb-dev/2008-March/004050.html Signed-off-by: Samuel CUELLA <samuel.cuella@supinfo.com> Cc: Jiri Kosina <jkosina@suse.cz> Cc: Krzysztof Helt <krzysztof.h1@poczta.fm> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>		2009-03-10 15:55:12 -07:00
