From 25bf6ce41d2692db2e991447015fb4bfbf3c3982 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Tue, 4 Jun 2013 13:40:42 +0200 Subject: rt2x00: add queue_init callback to rt2x00_ops The driver uses static data structures for initializing specific fields of a given data queue. These static queue data descriptor structures are containing values which related to a given chipset. Even though the values are chip specific, the actual selection of the used structure is based on device specific vendor/product identifiers. This approach works, but it is not always reliable. Sometimes the vendor and/or device IDs of the PCI and USB devices contains improper values which makes it impossible to select the correct structure for such devices. The patch adds a new callback to tr2x00_ops which is called after the chipset detection is finished. This allows the drivers to do dynamic initialization of the data_queue structure for a given queue based on the actual chipset. After each driver implements the queue_init callback, the data_queue_desc structure will be removed.
