Subject: [PATCH 1/4 v2] firmware: stratix10-svc: Fix genpool creation error handling
Date: Wed, 29 Apr 2020 08:52:34 +0200 [thread overview]
Message-ID: <660774ee8e63c03cb93a24d605c381eb0dce3b67.1588142343.git.christophe.jaillet@wanadoo.fr> (raw)
In-Reply-To: <cover.1588142343.git.christophe.jaillet@wanadoo.fr>
'svc_create_memory_pool()' returns an error pointer on error, not NULL.
Fix the corresponding test and return value accordingly.
Move the genpool allocation after a few devm_kzalloc in order to ease
error handling.
Fixes: 7ca5ce896524 ("firmware: add Intel Stratix10 service layer driver")
