When clang detects a non-boolean constant in a logical operation it generates a 'constant-logical-operand' warning. In ieee80211_try_rate_control_ops_get() the result of strlen(<const str>) is used in a logical operation, clang resolves the expression to an (integer) constant at compile time when clang's builtin strlen function is used. Change the condition to check for strlen() > 0 to make the constant operand boolean and thus avoid the warning.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
