Subject: nvme: move ->retries setup to nvme_setup_cmd
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=987f699a8f6c9a724e970c1bb4cde2e2c6a52010;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

nvme: move ->retries setup to nvme_setup_cmd

->retries is counting the number of times a command is resubmitted, and
be cleared on the first time we see the command.  We currently don't do
that for non-PCIe command, which is easily fixed by moving the setup
to common code.
