Subject: [PATCH] libertas: remove two libertas sparse warning
Date: Wed, 29 Oct 2008 10:35:02 +0100	[thread overview]
Message-ID: <200810291035.02763.hs4233@mail.mn-solutions.de> (raw)

Johannes Berg detected this two sparse warnings:

drivers/net/wireless/libertas/cmd.c:609:16: warning: cast to restricted __le16
drivers/net/wireless/libertas/cmd.c:611:16: warning: cast to restricted __le16

... but cmd.minlevel is "s8", so we can access it directly and hope
for the sign-extension-code in the compiler to convert that to the
"s16" type.
