Sascha Hauer b2b5921fe4 mtd: rawnand: initialize ntargets with maxchips
memorg->ntargets is initialized with '1'. It should be initialized with
the maxchips argument from nand_scan() instead. Otherwise multi chip
support errors out on the secondary chip selects when trying to call
nand_reset() on them:

WARNING: CPU: 0 PID: 1 at drivers/mtd/nand/raw/internals.h:114
nand_reset_op+0x194/0x1c4

With this memorg->ntargets is initialized with the maximum number of
chip selects supported by the driver. After having detected the number
of actually connected chips memory->ntargets is updated with that
number.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
