[PATCH v4 14/29] scsi: hisi_sas_v3_hw: Remove extra function calls for runtime pm

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

 



Both runtime_suspend_v3_hw() and runtime_resume_v3_hw() do nothing else but
invoke suspend_v3_hw() and resume_v3_hw() respectively. This is the case of
unnecessary function calls. To use those functions for runtime pm as well,
simply use UNIVERSAL_DEV_PM_OPS.

make -j$(nproc) W=1, with CONFIG_PM disabled, throws '-Wunused-function'
warning for runtime_suspend_v3_hw() and runtime_resume_v3_hw(). After
dropping those function definitions, the warning was thrown for
suspend_v3_hw() and resume_v3_hw(). Hence, mark them as '__maybe_unused'.
