No need to use expensive atomic change_bit() on dat[] and err_idx[]: 1. fsmc_bch8_correct_data() is called while mutex chip->lock is held 2. err_idx[] is a local variable. To avoid big endian concern due to type cast to unsigned long, directly change the bit in the specified byte instead of using non-atomic __change_bit().

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.
