Subject: mtd: nand: pxa3xx: Fix not calling dev_xxx with a device
X-Git-Url: http://git.dujemihanovic.xyz/%22http:/www.sics.se/static/%7B%7B%20%24style.Permalink%20%7D%7D?a=commitdiff_plain;h=661c98121d49c643a1b7b4427d152e2586a220b2;p=u-boot.git

mtd: nand: pxa3xx: Fix not calling dev_xxx with a device

Use the device from any mtd already available, or from the active mtd via
pxa3xx_nand_info if one is not.
