mtd: intflmount: fix off by one error in INFTL_dumpVUchains()
The ->PUtable[] array has "->nb_blocks" number of elemetns so this comparison should be ">=" instead of ">". Otherwise it could result in a minor read beyond the end of an array. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
