[PATCH] Fix dm9000 release_resource
dm9000_release_board calls release_resource with the platform resource
instead of the requested resource:
db->addr_res = platform_get_resource(pdev, IORESOURCE_MEM, 0);
db->addr_req = request_mem_region(db->addr_res->start, i, pdev->name);
dm9000_release_board:
if (db->addr_res != NULL) {
release_resource(db->addr_res);
kfree(db->addr_req);
With this behavior the kernel will crash on the second removal. The
attached patch fix this problem.
