Subject: USB: remove unnecessary tests in isp116x and sl811
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e39ab592f182cd0be48acc4ad49f93ef4100017c;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

USB: remove unnecessary tests in isp116x and sl811

This patch (as962) cleans up some code I forgot to remove earlier in
the isp116x and sl811 HCDs.  There is no longer any need to check for
unlink-during-submit; it can't happen since the endpoint queues are
now under the protection of the HCD-private spinlock.
