'rtl8192_irq_rx_tasklet()' is a tasklet initialized in
'rtl8192_init_priv_task()'.
>From this function it is possible to allocate some memory with the
GFP_KERNEL flag, which is not allowed in the atomic context of a tasklet.
Use GFP_ATOMIC instead.
The call chain is:
rtl8192_irq_rx_tasklet (in r8192U_core.c)
--> rtl8192_rx_nomal (in r8192U_core.c)
--> ieee80211_rx (in ieee80211/ieee80211_rx.c)
--> RxReorderIndicatePacket (in ieee80211/ieee80211_rx.c)
