Subject: target/avr: Fix interrupt execution
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=56b90e60c4019b08012bd8bd1459efc00b055577;p=qemu.git

target/avr: Fix interrupt execution

Only one interrupt is in progress at the moment.
It is only necessary to set to reset interrupt_request
after all interrupts have been executed.
