From: Bjorn Helgaas Date: Mon, 27 Mar 2006 09:17:04 +0000 (-0800) Subject: [PATCH] pnp: mpu401: adjust pnp_register_driver signature X-Git-Tag: v2.6.17-rc1~355 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f301ae6a690abe7edd2f92fa6df0b1b06986a6ad;p=pandora-kernel.git [PATCH] pnp: mpu401: adjust pnp_register_driver signature This series of patches removes the assumption that pnp_register_driver() returns the number of devices claimed. Returning the count is unreliable because devices may be hot-plugged in the future. (Many devices don't support hot-plug, of course, but PNP in general does.) This changes the convention to "zero for success, or a negative error value," which matches pci_register_driver(), acpi_bus_register_driver(), and platform_driver_register(). If drivers need to know the number of devices, they can count calls to their .probe() methods. This patch: Remove the assumption that pnp_register_driver() returns the number of devices claimed.
