Subject: IB/ipath: Fix error returned from ib_resize_cq if new size smaller than # entries
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=733d12813bd36ed7c727686ac1164f92f87a14a2;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

IB/ipath: Fix error returned from ib_resize_cq if new size smaller than # entries

The gen2_basic tests check for the errno value when a CQ is resized
smaller than the number of outstanding completions queue on the CQ.
This patch changes ib_ipath to return EINVAL which is what ib_mthca
returns and what gen2_basic expects.
