From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
[ Upstream commit 5836947613ef33d311b4eff6a32d019580a214f5 ]
The error handling path of mpc52xx_lpbfifo_probe() has a request_irq()
that is not balanced by a corresponding free_irq().
Add the missing call, as already done in the remove function.
Fixes: 3c9059d79f5e ("powerpc/5200: add LocalPlus bus FIFO device driver")
