From d489ff42db9179647004ca2b12c614cb71ac81ea Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Tue, 29 Sep 2015 17:28:44 -0700 Subject: Revert "mtd: mtdram: check offs and len in mtdram->erase" This reverts commit 7827e3acad2df1c6537e5fe7211d216dabc60399. There are some 64-bit arithmetic issues on some architectures, so let's wait until we get a better patch for this.
