Subject: [PATCH 2/3] media: radio: si470x: Fix DRIVER_AUTHOR macro definition

The DRIVER_AUTHOR macro incorrectly included a semicolon in its
string literal definition. Right now, this wasn't causing any real
problem, but coming changes to the MODULE_INFO() macro make this more
sensitive. Specifically, when used with MODULE_AUTHOR(), this created
syntax errors during macro expansion:

    MODULE_AUTHOR(DRIVER_AUTHOR);

expands to:

    MODULE_INFO(author, "Joonyoung Shim <jy0922.shim@...sung.com>";)
                                                                  ^
                                                       syntax error

Remove the trailing semicolon from the DRIVER_AUTHOR definition.
Semicolons should only appear at the point of use, not in the macro
definition.
