With logging enabled, it has been observed that the driver spews messages such as: wlcore: ERROR Calculate of clear addr Clear = 204025b0, write = 204015b0 The problem occurs because 204025b0 is the end of the buffer, and 204015b0 is the beginning, and the calculation for "clear"ing the buffer does not take into account that if we read to the very end of the ring buffer, we are actually at the beginning of the buffer. Fix this. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/E1lolvc-0003RM-VE@rmk-PC.armlinux.org.uk
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.
