Subject: m32r: Convert opsput irq chip
X-Git-Tag: firefly_0821_release~7613^2~2619^2~19
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=883c0ccde1e12e7721966626983d61ccdbd0ae99;p=firefly-linux-kernel-4.4.55.git

m32r: Convert opsput irq chip

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