From 2a1254f505ca4d376eae81768e4d5d890b578d13 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Thu, 14 Nov 2013 18:25:27 -0300 Subject: [PATCH 141/203] mtd: nand: pxa3xx: Use waitfunc() to wait for the device to be ready In pxa3xx_nand_sensing() instead of simply using info->is_ready after issuing a command, the correct way of checking is to wait for the device to be ready through the chip's waitfunc().
