[PATCH] platform/mellanox: mlxreg-lc: fix error code in mlxreg_lc_create_static_devices()

From: Dan Carpenter
Date: Wed Nov 10 2021 - 02:44:16 EST


This code should be using PTR_ERR() instead of IS_ERR(). And because
it's using the wrong "dev->client" pointer, the IS_ERR() check will be
false, meaning the function returns success.

Fixes: 62f9529b8d5c ("platform/mellanox: mlxreg-lc: Add initial support for Nvidia line card devices")
