* headers: separate linux/mod_devicetable.h from linux/platform_device.hRandy Dunlap2018-07-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | At over 4000 #includes, <linux/platform_device.h> is the 9th most #included header file in the Linux kernel. It does not need <linux/mod_devicetable.h>, so drop that header and explicitly add <linux/mod_devicetable.h> to source files that need it. 4146 #include <linux/platform_device.h> After this patch, there are 225 files that use <linux/mod_devicetable.h>, for a reduction of around 3900 times that <linux/mod_devicetable.h> does not have to be read & parsed. 225 #include <linux/mod_devicetable.h> This patch was build-tested on 20 different arch-es. It also makes these drivers SubmitChecklist#1 compliant.

| * ata: use CONFIG_PM_SLEEP instead of CONFIG_PM where applicable in host driversBartlomiej Zolnierkiewicz2014-05-091-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes host drivers to use CONFIG_PM_SLEEP instead of CONFIG_PM where applicable. Benefits of this change: * unused code is not being compiled in for CONFIG_PM=y, CONFIG_PM_SLEEP=n and CONFIG_PM_RUNTIME=y configurations * easier transition to use struct dev_pm_ops and SIMPLE_DEV_PM_OPS() in the future * more consistent code (there are host drivers which are using the correct CONFIG_PM_SLEEP checks already) The patch leaves the core libata code and ->port_[suspend,resume] support in sata_[inic162x,nv,sil24].c alone for now.
