I see a new compiler warning:

drivers/net/wireless/ath/ath10k/wmi.c: In function
'ath10k_wmi_event_service_ready_work':
drivers/net/wireless/ath/ath10k/wmi.c:4347:30: warning: 'pool_size' may
be used uninitialized in this function [-Wuninitialized]
drivers/net/wireless/ath/ath10k/wmi.c:4319:6: note: 'pool_size' was
declared here

Seems to be false and maybe because my gcc is pretty old:

gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3

But anyway it would be nice if this can be avoided.
