Subject: m32r: Convert m32104ut irq handling
X-Git-Url: https://git.karo-electronics.de/?p=mv-sheeva.git;a=commitdiff_plain;h=8afb53b9ac0ac196d58b741d7bdfba8702ae7945

m32r: Convert m32104ut irq handling

Convert the irq chips to the new functions and use proper flow
handlers. handle_level_irq is appropriate.
