[PATCH 04/12] rtc: mv: Mark driver struct with __refdata to prevent section mismatch warning

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 a section mismatch warning.
