Subject: [S390] qdio: continue polling if the queue is not finished
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e2910bcf8ca762b306767a0894ab1987be014c9e;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[S390] qdio: continue polling if the queue is not finished

With commit c38f96080955854e54df9cb392bc674e1ae330e1 polling was
stopped for the queue even if new data is available.

Return immediately after scheduling the queue tasklet if the queue
is not done.
