fbdev: Don't re-validate info->state in fb_ops implementations
Thomas Zimmermann authored

The file-op entry points fb_read() and fb_write() verify that
info->state has been set to FBINFO_STATE_RUNNING. Remove the same
test from the implementations of struct fb_ops.{fb_read,fb_write}.

v2:
	* also remove test from ivtvfb, braodsheetfb, hecubafb and
	  metronomefb (Geert)

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.
