Subject: [PATCH 6/17] drivers/char/riscom8: irq handler cleanups

commit 93ea6d56f83b7b614c103222fa098cb30d26f608

    drivers/char/riscom8: irq handler cleanups
    
    No need to lookup board ptr, we already have it.
    
    Also, remove a few 'inline' markers and let the compiler make that
    decision.
