2.6.37-stable review patch. If anyone has any objections, please let us know.
------------------ From: Dan Carpenter <[email protected]> commit 52d039fdaa78c5a9f9bc2940ad58d7ed76b8336d upstream. "info->cmdset" gets dereferenced in __readid() so it needs to be initialized earlier in the function. This bug was introduced in 18c81b1828f8 "mtd: pxa3xx_nand: remove the flash info in driver structure".
