Subject: nvme-fc: remove unused "queue_size" field
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=08e1507544839b98fc3732aea935e70ed9c209ec;p=linux.git
nvme-fc: remove unused "queue_size" field
This was being saved in a structure, but never used anywhere. The queue
size is obtained through other means, so there's no reason to duplicate
this without a user for it.
