Analyze and fix the following issue in the Linux kernel code: Fix crash with irqpoll due to the IRQF_IRQPOLL flag testing
Problem Details: With irqpoll enabled, trying to test the IRQF_IRQPOLL flag in the actions would cause a NULL pointer dereference if no action was installed (for example, the driver might have been unloaded with interrupts still pending). So be a bit more careful about testing the flag by making sure to test for that ...

Analyze and fix the following issue in the Linux kernel code: USB: Fix debug output of ark3116
Problem Details: Fix debug output. Previously, it would output "0xFFFFFFB0" on 32-bit archs (and probably "0xFFFFFFFFFFFFFFB0" on 64-bits), because buf is taken as signed char, which is promoted to signed int, while %x always expects an unsigned int.
