For example drivers aren't supposed to handle PCI state transitions themselves. This is all provided by the PCI bus core already. In addition to that there is no point scheduling RPM suspend on driver's idle hook but instead we can use RPM autosuspend for this (which is enabled in the driver already). As a bonus, this patch also fixes following compile warning which is emitted when the driver was compiled without CONFIG_PM_RUNTIME set: drivers/i2c/busses/i2c-designware-pcidrv.c:245:12: warning: ‘i2c_dw_pci_runtime_idle’ defined but not used [-Wunused-function] Reported-by: xinhui.pan Reported-by: Jingoo Han Signed-off-by: Mika Westerberg Signed-off-by: Wolfram Sang --- Reading git-diff-tree failed
