This patch corrects the SPDX License Identifier style in header files related to Clock Drivers for Actions Semi Socs. 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 Suggested-by: Joe Perches <joe@perches.com> Signed-off-by: Nishad Kamdar <nishadkamdar@gmail.com> Signed-off-by: Stephen Boyd <sboyd@kernel.org>
