The patch titled
mtd: hot spin and code duplication in nand_bcm_umi_bch_read_oobEcc()
has been removed from the -mm tree. Its filename was
mtd-hot-spin-and-code-duplication-in-nand_bcm_umi_bch_read_oobecc.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: mtd: hot spin and code duplication in nand_bcm_umi_bch_read_oobEcc()
From: Roel Kluin <roel.kluin@xxxxxxxxx>
In the branch where pagesize equalled NAND_DATA_ACCESS_SIZE, NumToRead
wasn't decremented in the `while (numToRead > 11)' loop. Also the first
and last while loops were duplicated in both branches.
