Merge patch series "scsi: Prevent several section mismatch warnings"

Uwe Kleine-König <u.kleine-koenig@pengutronix.de> says:

Hello,

this series fixes the same issue in four drivers. The warning is a false
positive and to suppress it the driver structs are marked with
__refdata and a comment is added to describe the (non-trivial)
situation.

Best regards
Uwe
