Subject: nvme: delete dev from dev_list in nvme_reset
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=201cf1ecdfe5ea2774cbb21d4214c98ec8b418de;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

nvme: delete dev from dev_list in nvme_reset

Device resets need to delete the device from the device list before
kicking of the reset an re-probe, otherwise we get the device added
to the list twice.  nvme_reset is the only side missing this deletion
at the moment, and this patch adds it.
