Re: [microblaze-uclinux] xilinx_gpio driver patch

When configuring my system with three Xilinx Gpio devices using
drivers/char/xilinx_gpio, my system would hang during bootup. I isolated the
problem to the xilinx_gpio driver, on an error condition in xgpio_probe.
When the second device was probed, the request_irq failed leaving the
inst_list_sem locked, so when the third probe started it blocked on
acquiring the lock.
Nice detective work - thanks for the patch.
