Kunwu Chan cb8ff060a5 ARM: OMAP2+: Fix null pointer dereference and memory leak in omap_soc_device_init
[ Upstream commit c72b9c33ef9695ad7ce7a6eb39a9df8a01b70796 ]

kasprintf() returns a pointer to dynamically allocated memory which can
be NULL upon failure. When 'soc_dev_attr->family' is NULL,it'll trigger
the null pointer dereference issue, such as in 'soc_info_show'.

And when 'soc_device_register' fails, it's necessary to release
'soc_dev_attr->family' to avoid memory leaks.
