* ocxl: Use the correct style for SPDX License IdentifierNishad Kamdar2019-10-101-1/+1
| | | | | | | | | | | | | | | | | This patch corrects the SPDX License Identifier style in header files for Open Coherent Accelerator (OCXL) compatible device drivers. For C header files Documentation/process/license-rules.rst mandates C-like comments (opposed to C source files where C++ style should be used) Changes made by using a script provided by Joe Perches here: https://lkml.org/lkml/2019/2/7/46.
