This is not a readability improvment.  I would factor it out into its
own function.

Also not a readability improvement.  This checkpatch warning should
be disregarded.

Copy the code into a new function.  Then see what parameters this function
needs for the various information it requires.  The code will produce some
results that are needed by the rest of the program.  So you have to
arrange via the return value that the proper variables are initialized
after the function call.

For example,

x = a + b;

could become

int f(int a, int b) {
  return a + b;
}

x = f(a,b);

That is a pretty silly change, but it gives the idea.

As several other people already commented, these changes do not improve readability.
Just leave this code alone, it's good enough. Even splitting up the condition into
a separate function would degrade readability since that would make it harder to
discover the exact condition that will be polled for.

Not everything that checkpatch.pl flags is necessarily bad code :-)

These, however, are readability improvements, so I'm happy with that.
