mainlining shenanigans
55e58c5e78
With gcc 4.1:
drivers/lightnvm/core.c: In function ‘nvm_get_bb_meta’:
drivers/lightnvm/core.c:977: warning: ‘ret’ may be used uninitialized in this function
and
drivers/nvme/host/lightnvm.c: In function ‘nvme_nvm_get_chk_meta’:
drivers/nvme/host/lightnvm.c:580: warning: ‘ret’ may be used uninitialized in this function
Indeed, if (for the former) the number of channels or LUNs is zero, or
(for both) the passed number of chunks is zero, ret will be returned
uninitialized.
Fix this by preinitializing ret to zero.

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.
