Subject: nvme: centralize ctrl removal prints
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=77d0612da0e61cb2903ecd0be02444e4c958c672;p=linux.git

nvme: centralize ctrl removal prints

nvme_delete_ctrl can be called from various contexts in parallel,
and cause duplicated information prints, even though the specific
context doesn't perform the actual removal. Instead, print the
information when the actual removal occurs.
