parisc fix for kernel v4.19

Hi Greg,

would you please include the trivial patch below for 4.19?
My older cross-compiler didn't complained, so it went unnoticed for me until now and the faulty code was added during the 4.19 merge window.

It can be pulled from my git tree as well:

git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-4.19-3

Fix an unitialized variable usage in the parisc unwind code.

Thanks,
Helge

Subject: parisc: Fix uninitialized variable usage in unwind.c

As noticed by Dave Anglin, the last commit introduced a small bug where the potentially uninitialized r struct is used instead of the regs pointer as input for unwind_frame_init(). Fix it.

+		unwind_frame_init(info, task, regs);
 	} else {

Now merged, thanks.
