Subject: [PATCH] rtlwifi: Align private space in rtl_priv struct
Date: Wed, 18 Sep 2013 21:21:35 -0500 [thread overview]
Message-ID: <1379557295-18484-1-git-send-email-Larry.Finger@lwfinger.net> (raw)
The private array at the end of the rtl_priv struct is not aligned.
On ARM architecture, this causes an alignment trap and is fixed by aligning
that array with __align(sizeof(void *)). That should properly align that
space according to the requirements of all architectures.
