[ Upstream commitafdc74ed2d] r375326 in Clang exposes an issue with operator precedence in sunxi_div_clk_setup: drivers/clk/sunxi/clk-sunxi.c:1083:30: warning: operator '?:' has lower precedence than '|'; '|' will be evaluated first [-Wbitwise-conditional-parentheses] data->div[i].critical ? ~~~~~~~~~~~~~~~~~~~~~ ^ drivers/clk/sunxi/clk-sunxi.c:1083:30: note: place parentheses around the '|' expression to silence this warning data->div[i].critical ? ^ ) drivers/clk/sunxi/clk-sunxi.c:1083:30: note: place parentheses around the '?:' expression to evaluate it first data->div[i].critical ? ^ ( 1 warning generated. It appears that the intention was for ?: to be evaluated first so that CLK_IS_CRITICAL could be added to clkflags if the critical boolean was set; right now, | is being evaluated first. Add parentheses around the ?: block to have it be evaluated first.

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.
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.
