Subject: [PATCH 1/3] media: dvb-usb-v2: lmedm04: Fix firmware macro definitions

The firmware filename macros incorrectly included semicolons in their
string literal definitions. 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_FIRMWARE(), this
created syntax errors during macro expansion:

    MODULE_FIRMWARE(LME2510_C_S7395);

expands to:

    MODULE_INFO(firmware, "dvb-usb-lme2510c-s7395.fw";)
                                                     ^
                                          syntax error

Remove the trailing semicolons from all six firmware filename macro
definitions. Semicolons should only appear at the point of use, not in
the macro definition.
