OSS: dmasound/paula: Mark driver struct with __refdata to prevent section mismatch
[ Upstream commit 755795cd3da053b0565085d9950c44d7b6cba5c4 ]
As described in the added code comment, a reference to .exit.text is ok
for drivers registered via module_platform_driver_probe(). Make this
explicit to prevent the following section mismatch warning
WARNING: modpost: sound/oss/dmasound/dmasound_paula: section mismatch in reference: amiga_audio_driver+0x8 (section: .data) -> amiga_audio_remove (section: .exit.text)
that triggers on an allmodconfig W=1 build.
