[PATCH] sata_fsl: Fix a resource leak in an error handling path in the probe function

From: Christophe JAILLET
Date: Sat Dec 12 2020 - 08:01:55 EST


'irq_dispose_mapping()' should be called in the error handling path of the
probe function, as already done in the remove function.

Fixes: 6b4b8fc87dc5 ("sata_fsl: add support for interrupt coalsecing feature")
