Subject[PATCH] drivers/mmc/mmc.c: Replacing yield() with a better alternative
From
Date
In 2.6, the semantics of calling yield() changed from "sleep for a
bit" to "I really don't want to run for a while". This matches POSIX
better, but there's a lot of drivers still using yield() when they mean
cond_resched(), schedule() or even schedule_timeout().

For this driver cond_resched() seems to be a better
alternative

Tested compile only
