[PATCH] crypto: ccp - Fix a resource leak in an error handling path

From: Christophe JAILLET
Date: Sun May 16 2021 - 02:58:34 EST


If an error occurs after calling 'sp_get_irqs()', 'sp_free_irqs()' must be
called as already done in the error handling path.

Fixes: f4d18d656f88 ("crypto: ccp - Abstract interrupt registeration")
