mtd: nand: pxa3xx: Use waitfunc() to wait for the device to be ready

ezequielgarcia · computersforpeace · commit 56704d857ac9 · 2014-01-03T11:22:11.000-08:00
In pxa3xx_nand_sensing() instead of simply using info-&gt;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().
