Subject: [PATCH] mtd: lpc32xx: drop bitflip_threshold initialization
Date: Wed, 28 May 2014 01:52:25 -0700 [thread overview]
Message-ID: <1401267145-18218-1-git-send-email-computersforpeace@gmail.com> (raw)
These drivers don't need to explicitly initialize their bitflip
thresholds. The comment is no longer correct, since nand_scan_tail()
performs this initialization as of the following commit:
commit ea3b2ea24ef0f2ef9c6795b19cff456195b6728a
Author: Shmulik Ladkani <shmulik@jungo.com>
Date: Fri Jun 8 18:29:06 2012 +0300
mtd: nand: initialize bitflip_threshold prior to BBT scanning
(It seems there were some parallel efforts on writing/submitting these
drivers, and Shmulik's bug fix.)
