Subject: [PATCH] posix-clock: Use an unsigned data type for a variable

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 20 Dec 2015 09:09:34 +0100

The data type "int" was used by the variable "result" in the
function "posix_clock_poll" even though the type "uint" will usually
be needed for the return value from a call of the function which was
assigned to the pointer "poll" of the variable "clk".
Reuse the type from this poll call instead.

This issue was detected by using the Coccinelle software.
