Subject: RDMA/qedr: Fix rc initialization on CNQ allocation failure
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8ed753eee9bdf091a2ca2541451b42717de7e781;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

RDMA/qedr: Fix rc initialization on CNQ allocation failure

[ Upstream commit b15606f47b89b0b09936d7f45b59ba6275527041 ]

Return code wasn't set properly when CNQ allocation failed.
This only affect error message logging, currently user will
receive an error message that says the qedr driver load failed
with rc '0', instead of ENOMEM

Fixes: ec72fce4 ("qedr: Add support for RoCE HW init")
