smp_call_function_single disables IRQs when executing the callback. To prevent deadlocks, we must disable IRQs when taking cgr_lock elsewhere. This is already done by qman_update_cgr and qman_delete_cgr; fix the other lockers.

I got no response the first time I sent this, so I am resending to net. This issue was introduced in a series which went through net, so I hope it makes sense to take it via net.

(no changes since v3)
Changes in v3:
- Change blamed commit to something more appropriate
Changes in v2:
- Fix one additional call to spin_unlock
Leo Li (Li Yang) is no longer with NXP. Until we figure out within NXP how to continue with the maintainership of drivers/soc/fsl/, yes, please continue to submit this series to 'net'. I would also like to point out to Arnd that this is the case.
Arnd, a large portion of drivers/soc/fsl/ is networking-related (dpio, qbman). Would it make sense to transfer the maintainership of these under the respective networking drivers, to simplify the procedures?
Also, your patches are whitespace-damaged. They do not apply to the kernel, and patchwork shows this as well. https://cas5-0-urlprotect.trendmicro.com:443/wis/clicktime/v1/query?url=http...
Please repost with this fixed.
Hm, I used the same method I have in the past (git send-email). But I guess something is converting my tabs to spaces? Maybe it is related to the embedded world advertisement...
Maybe the solution is to get a kernel.org email...
