- Subject: rtlwifi: Align private space in rtl_priv struct
- 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.
