No idea why con2fb_acquire_newinfo() initializes much less than fbcon_startup(), but so be it. From a quick look most of the un-initialized stuff should be fairly harmless, but who knows. Note that the error handling for the con2fb_acquire_newinfo() failure case was very strange: Callers updated con2fb_map to the new value before calling this function, but upon error con2fb_acquire_newinfo reset it to the old value. Since I removed the call to fbcon_release anyway that strange error path was sticking out like a sore thumb, hence I removed it. Which also allows us to remove the oldidx parameter from that function. v2: Explain what's going on with oldidx and error paths (Sam) v3: Drop unused variable (0day) v4: Rebased over bisect fix in previous patch, unchagend end result.

README
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.
