[media] as102: add __packed attribute to structs defined inside packed structs
This patch fixes a regression in kernel 3.3 due to this patch: http://patchwork.linuxtv.org/patch/8332/ That patch changes "#pragma pack(1)" with "__packed" attributes, but it is not complete. In fact, in the as102 driver there are a lot of structs/unions defined inside other structs/unions. When the "__packed" attribute is applied only on the external struct, it will not affect the internal struct definitions. So the regression is fixed by specifiying the "__packed" attribute also on the internal structs. This patch should go into 3.3, as it fixes a regression introduced in the new kernel version.
