X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=88ad1a147e2c84d33cb50f5ebff1ece5e0cd4383;p=linux-beck.git lguest: fix pending interrupt test. Denys says: TEST with zero will always set ZF. Thus, "jnz send_interrupts" never jumps. We get interrupts regularly enough that this didn't cause immediate problems.
