Subject: ide: ide_requeue_and_plug() reinstate "always plug" behaviour
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=929e27252e8ca69363f81f26af5eaba62cb4c572;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

ide: ide_requeue_and_plug() reinstate "always plug" behaviour

We see stalls if we don't always ensure that the queue gets run
again. Even if rq == NULL, we could have other pending requests
in the queue.
