staging: Additional item for rtl8188eu TODO list
The rtw_recv_indicatepkt() function in the file named
drivers/staging/rtl8188eu/os_dep/recv_linux.c has this strange code:
rcu_read_lock();
rcu_dereference(padapter->pnetdev->rx_handler_data);
rcu_read_unlock();
This code has no effect. Normally, you would assign the result of
rcu_dereference() to some variable, but it is not clear from the
code what variable that would be. Therefore, this patch applies to
the TODO file instead of the code itself.

+- figure out what to do with this code in rtw_recv_indicatepkt():
+ rcu_read_lock();
+ rcu_dereference(padapter->pnetdev->rx_handler_data);
+ rcu_read_unlock();
+ Perhaps delete it, perhaps assign to some local variable.
