media: s5p-mfc: remove an unused/uninitialized variable

Browse source

commit 7fa37ba25a upstream.

The s5p_mfc_cmd_args structure in the v6 driver is never used, not
initialized to anything other than zero, but as of clang-21 this
causes a warning:

drivers/media/platform/samsung/s5p-mfc/s5p_mfc_cmd_v6.c:45:7: error: variable 'h2r_args' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer]
   45 |                                         &h2r_args);
      |                                          ^~~~~~~~

Just remove this for simplicity. Since the function is also called
through a callback, this does require adding a trivial wrapper with
the correct prototype.
