Subject: netconsole: do not release spin_lock when calling __netpoll_cleanup
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3335f0ca130c201f8680e97f63612053fbc16e22;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

netconsole: do not release spin_lock when calling __netpoll_cleanup

With the previous patch applied, __netpoll_cleanup() is non-block now,
so we don't need to release the spin_lock before calling it.
