From: Sylvain Munaut Date: Wed, 13 Dec 2006 20:09:54 +0000 (+0100) Subject: ohci: Rework bus glue integration to allow several at once X-Git-Tag: v2.6.21-rc1~92^2~29^2~51 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5e16fabe5dbcff15de6cdcba406195fe6e4380df;p=linux-2.6 ohci: Rework bus glue integration to allow several at once The previous model had the module_init & module_exit function in the bus glue .c files themselves. That's a problem if several glues need to be selected at once and the driver is built has module. This case is quite common in embedded system where you want to handle both the integrated ohci controller and some extra controller on PCI. The ohci-hcd.c file now provide the module_init & module_exit and appropriate driver registering/unregistering is done conditionally, using #ifdefs.
