Subject: [patch 10/18] net/g96100eth: replace gt96100_delay() with msleep_interruptible()

From: [email-masked]
Date: Sun, 31 Oct 2004 00:42:49 +0200

Any comments would be appreciated.

Description: Use msleep_interruptible() instead of gt96100_delay() so
that the task delays as expected. Remove the prototype and definition of
gt96100_delay(). As I currently understand it, the check for interrupt
context is not necessary in gt96100_delay(), as such a sleep will be
caught within the scheduler.
