Subject: [PATCH] soc: qcom: cmd-db: Fix an error code in cmd_db_dev_probe()
Date: Thu, 28 Feb 2019 05:48:49 +0000 [thread overview]
Message-ID: <20190228054849.GD3253@kadam> (raw)
The memremap() function doesn't return error pointers, it returns NULL.
This code is returning "ret = PTR_ERR(NULL);" which is success, but it
should return -ENOMEM.
Fixes: 312416d9171a ("drivers: qcom: add command DB driver")
