Is there a list anywhere of the kinds of drivers that are allowed to use devm functions? I know that it is possible for platform drivers, but by tracing backwards from calls to eg the platform driver probe function, it was not easy to see why this was so - one seems to run into several levels of functions pointers, that I didn't bother tracing through. Perhaps I have missed something obvious. As an approximation, I collected the entry points (functions stored insome data structure) for which there is at least one definition that calls devm_kzalloc. The list on a moderately recent linux-next is as follows: amba_driver.probe ata_port_operations.port_start drm_driver.load dw_mci_drv_data.init ecard_driver.probe hid_driver.input_configured hid_driver.probe i2c_driver.probe iio_info.update_scan_mode iommu_ops.attach_dev macio_driver.probe mipi_dsim_lcd_driver.probe pci_driver.probe pcmcia_driver.probe pinctrl_ops.dt_node_to_map platform_driver.probe pwm_ops.request sdio_driver.probe sh_pfc_soc_operations.init snd_soc_codec_driver.probe spi_driver.probe usb_driver.probe v4l2_subdev_internal_ops.registered thanks, julia -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
