[PATCH 5.10 099/122] gpio: mpc8xxx: Fix a resources leak in the error handling path of mpc8xxx_probe()

[Greg Kroah-Hartman]

From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>

[ Upstream commit 555bda42b0c1a5ffb72d3227c043e8afde778f1f ]

Commit 698b8eeaed72 ("gpio/mpc8xxx: change irq handler from chained to normal")
has introduced a new 'goto err;' at the very end of the function, but has
not updated the error handling path accordingly.

Add the now missing 'irq_domain_remove()' call which balances a previous
'irq_domain_create_linear() call.

Fixes: 698b8eeaed72 ("gpio/mpc8xxx: change irq handler from chained to normal")
