[PATCH 04/16] staging: sm750fb: add proper SPDX identifier to driver

[Greg Kroah-Hartman]

By default all files without license information are under the default
license of the kernel, which is GPL version 2.  Because of this, add the
GPL-2.0 identifier to the sm750fb driver which did not have any license
identifiers in it at all.
