From 3d76e82c9538d8104e578ca460d35f214bfddfd3 Mon Sep 17 00:00:00 2001 From: Lennert Buytenhek Date: Thu, 22 Oct 2009 20:20:16 +0200 Subject: [PATCH] mwl8k: use cond_resched() when loading firmware blocks Since each firmware block takes on the order of several hundred usec to upload to the hardware, using msleep in the inner loop would make the firmware loading process take a lot more time than just doing busy-waiting like we do now. But if we keep the busy-waiting, we can at least add a cond_resched() to the inner loop so that we give other tasks a chance to run while the firmware is being loaded.
