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. Signed-off-by: Randy Dunlap <rdunlap@infradead.org> Reported-by: kbuild test robot <lkp@intel.com> # drivers/media/platform/vimc/ Reported-by: kbuild test robot <lkp@intel.com> # drivers/pinctrl/pinctrl-u300.c Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
