Subject: [PATCH] powerpc/pseries/hvcserver: Fix endian issue in hvcs_get_partner_info
Date: Tue, 5 Aug 2014 16:42:39 -0500 [thread overview]
Message-ID: <1407274959-20501-1-git-send-email-tlfalcon@linux.vnet.ibm.com> (raw)
A buffer returned by H_VTERM_PARTNER_INFO contains device information
in big endian format, causing problems for little endian architectures.
This patch ensures that they are in cpu endian.
