Subject: [PATCH] crypto: ccp - Fix a resource leak in an error handling path
Git-commit: a6f8e68e238a15bb15f1726b35c695136c64eaba
Patch-mainline: v5.14-rc1
References: git-fixes
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")
