From: Greg Kroah-Hartman <gregkh@xxxxxxx> This patch introduces the module_pci_driver macro which is a convenience macro for PCI driver modules similar to module_platform_driver. It is intended to be used by drivers which init/exit section does nothing but register/unregister the PCI driver. By using this macro it is possible to eliminate a few lines of boilerplate code per PCI driver. Based on work done by Lars-Peter Clausen <lars@xxxxxxxxxx> for other busses (i2c and spi). Cc: Lars-Peter Clausen <lars@xxxxxxxxxx> Signed-off-by: Greg Kroah-Hartman <gregkh@xxxxxxx> --- Jesse, I've added the same type of macros for i2c, spi, and usb to my driver-core tree, and converted a number of drivers to these new macros. If you give me the ack, I can add this patch to my tree as well. I'll follow up this patch with an example showing how it works.
