Date: Tue, 22 Jan 2013 09:30:30 +0800 From: Huang Shijie <b32955@...escale.com> To: <dwmw2@...radead.org> CC: <dedekind1@...il.com>, <matthieu.castet@...rot.com>, <linux-mtd@...ts.infradead.org>, <linux-kernel@...r.kernel.org>, Huang Shijie <b32955@...escale.com> Subject: [PATCH v2] mtd: fix the wrong timeo for panic_nand_wait() In nand_wait(), the timeo for panic_nand_wait() is assigned with wrong value(jiffies + some delay). The timeo should be set like the panic_nand_write() does. This patch fixes it, and also uses the msecs_to_jiffies() to make the code more readable.
