[yocto] [PATCH] Fix for psplash segmentation fault

[Aws Ismail]

Hi all,

This is a follow-up on the fix I sent recently for psplash. I'd
appreciate any comments.

Thanks

====================================================================
Fix psplash segmentation fault

This fixes the segmentation fault when calling:
psplash -a

The -a option requires a rotation angle to be given
and if it is missing then the user is shown the correct usage.
