[PATCH 6.2 493/663] firmware: stratix10-svc: Fix an NULL vs IS_ERR() bug in probe

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

[ Upstream commit e1d6ca042e62c2a69513235f8629eb6e62ca79c5 ]

The svc_create_memory_pool() function returns error pointers.  It never
returns NULL.  Fix the check.

Fixes: 7ca5ce896524 ("firmware: add Intel Stratix10 service layer driver")
