Subject: [PATCH] IPMI: return correct value from ipmi_write
X-Git-Tag: v2.6.26~18^2
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=3976df9b04c113ab19dc0268e49c6cec6baf28f7;p=linux-2.6-omap-h63xx.git

[PATCH] IPMI: return correct value from ipmi_write

This patch corrects the handling of write operations to the IPMI watchdog
to work as intended by returning the number of characters actually
processed. Without this patch, an "echo V >/dev/watchdog" enables the
watchdog if IPMI is providing the watchdog function.
