To comply with latest kernel code requirement, change printk() to counterpart pr_ functions in mtdoops driver: - change printk(INFO) to pr_info() - change printk(DEBUG) to pr_debug() - change printk(WARNING) to pr_warn() - change printk(ERR) to pr_err() Note that only if dynamic debugging is enabled or DEBUG is defined, printk(KERN_DEBUG) and pr_debug() are equivalent; Otherwise pr_debug() is no-op, causing different behavior.

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.
