[ Upstream commit d1f0a9816f5fbc1316355ec1aa4ddfb9b624cca5 ]
In function ‘fortify_memcpy_chk’, inlined from ‘get_conn_info_complete’ at net/bluetooth/mgmt.c:7281:2: include/linux/fortify-string.h:592:25: error: call to ‘__read_overflow2_field’ declared with attribute warning: detected read beyond size of field (2nd parameter); maybe use struct_group()? [-Werror=attribute-warning] 592 | __read_overflow2_field(q_size_field, size); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ cc1: all warnings being treated as errors
This is due to the wrong member is used for memcpy(). Use correct one.
