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. Signed-off-by: Jack Morgenstein Signed-off-by: David S.
