[PATCH] cxl: Fix an error message
From: Christophe JAILLET
Date: Wed May 05 2021 - 15:39:03 EST
'rc' is known to be 0 here.
Initialize 'rc' with the expected error code before using it.
While at it, avoid the affectation of 'rc' in a 'if' to make things more
obvious and linux style.
Fixes: f204e0b8ce ("cxl: Driver code for powernv PCIe based cards for userspace access")
