[PATCH] video: fbdev: pvr2fb: fix compile-testing as module

Building an allmodconfig kernel now produces a harmless warning:

drivers/video/fbdev/pvr2fb.c:726:12: error: unused function 'pvr2_get_param_val' [-Werror,-Wunused-function]

Shut this up the same way as we do for other unused functions
in the same file, using the __maybe_unused attribute.

Fixes: 0f5a5712ad1e ("video: fbdev: pvr2fb: add COMPILE_TEST support")

Thanks but I've fixed it already by adding #ifndef MODULE (since other
functions in the same file using __maybe_unused depend on either PCI or
SH_DREAMCAST I've preferred not to use this attribute):

Ok, dropping my patch from the local queue, your version is obviously
correct as well.
