The patch titled rt2860: possible NULL dereferences has been removed from the -mm tree. Its filename was rt2860-possible-null-dereferences.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: rt2860: possible NULL dereferences From: Roel Kluin <roel.kluin@xxxxxxxxx> Allocations may fail, prevent NULL dereferences. Remaining bug: in drivers/staging/rt2860/rt_main_dev.c rt28xx_probe() `handle' isn't freed in the case of later errors.
