From 4f41e7ea1a17ba7207ca41379bf344b317e72c12 Mon Sep 17 00:00:00 2001 From: Sandeep Paulraj Date: Sat, 7 Nov 2009 14:24:06 -0500 Subject: [PATCH] NAND: Correct the "chip_shift" calculation This patch updates the "chip_shift" calculation in the NAND driver. This is being done to sync up the NAND driver with the kernel NAND driver.
