Fwd: [patch 1/8] net/xirc2ps_cs: replace Wait() with msleep()

[Russell King]

This patch is probably more appropriate for jgarzik to handle
than myself (if not already done so.)  The same applies to any
other PCMCIA network driver patches.

Subject: [patch 1/8]  net/xirc2ps_cs: replace 	Wait() with msleep()
To: rmk+lkml@arm.linux.org.uk
Cc: akpm@osdl.org, linux-kernel@vger.kernel.org,
	janitor@sternwelten.at, nacc@us.ibm.com
From: janitor@sternwelten.at
Date: Sun, 31 Oct 2004 00:46:59 +0200




Any comments would be appreciated.

Description: Use msleep() instead of Wait() to guarantee the task delays
as expected. Remove definition of Wait().
