Subject: mlx4_core: fix bug in modify_cq wrapper for resize flow.
X-Git-Tag: v5.15~23017^2~4
X-Git-Url: https://git.proxmox.com/?a=commitdiff_plain;h=dcf353b17007841f91e1735e33790508c84c9ad0;p=mirror_ubuntu-kernels.git

mlx4_core: fix bug in modify_cq wrapper for resize flow.

The actual FW command is called in procedure "handle_resize".
Code incorrectly invoked the FW command again (in good flow), in
the modify_cq wrapper function.

Fix by skipping second FW invocation unconditionally for resize.
