Fix bug in end absolute address in drivers/mtd/devices/slram.c

2012-09-20 Thread Jiri Engelthaler 
Hello.
  I found a bug in parsing end absolute address in
drivers/mtd/devices/slram.c. There is checking for startaddress <
endaddress and endaddress subtracted by startaddress before check. The
bug is there from commit 3afd522de8d8ec446efe957b86e4f63e3dd8ce9d Mon,
19 Jan 2009 01:24:21 +

Here is the patch
