Subject[PATCH 2/4] crypto: ux500: Adjust two condition checks in ux500_cryp_probe()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 14 Feb 2018 10:38:44 +0100

The local variable "cryp_error" was used only for two condition checks.

* Check the return values from these function calls directly instead.

* Delete this variable which became unnecessary with this refactoring.
