Subject: [PATCH 4.4 144/312] mmc: moxart: fix wait_for_completion_interruptible_timeout return variable type

From: Nicholas Mc Guire <hofrat@...dl.org>

commit 41f469cac2663a41a7b0c84cb94e8f7024385ae4 upstream.

wait_for_completion_timeout_interruptible returns long not unsigned long
so dma_time, which is used exclusively here, is changed to long.

Fixes: 1b66e94e6b99 ("mmc: moxart: Add MOXA ART SD/MMC driver")
