Hello Jean,
I'm working again on virtual i2c adapter support :) since I received
several letters asking for this support. That's why I'd like to have
from you some advice in order to propose a working code.
Looking at latest i2c code I suppose we can modify the
i2c_del_driver() function as follow:
diff --git a/drivers/i2c/i2c-core.c b/drivers/i2c/i2c-core.c
index b1c9abe..3454878 100644
--- a/drivers/i2c/i2c-core.c
+++ b/drivers/i2c/i2c-core.c
@@ -799,10 +799,10 @@ void i2c_del_driver(struct i2c_driver *driver)
class_for_each_device(&i2c_adapter_class, NULL, driver,
__detach_adapter);
+ mutex_unlock(&core_lock);
+
driver_unregister(&driver->driver);
pr_debug("i2c-core: driver [%s] unregistered\n",
driver->driver.name);
-
- mutex_unlock(&core_lock);
}
EXPORT_SYMBOL(i2c_del_driver);
Unluckely I'm not an i2c guru so I'd like to ask to you. If such
modification is correct I can provide a simple support with no
modifications to the i2c core! Apart this one, of course... :)
If you agree I can send a patchset, but everything is based on the
above change...
Thanks for your suggestions,
Rodolfo
