You mean this :

+ /*
+ * Need to check request_firmware should be called only once
+ * so you don't leak memory if there is more than one NIC.
+ * Need to check if PCI probing gets multi-threaded as
+ * mutex is used while loading the firmware.
+ */
+ if (typhoon_fw != NULL) {
+ err = typhoon_init_firmware(tp);
This is not required now, As I already fixed request_firmware.

So it is replaced by :

+ err = typhoon_init_firmware(tp);

Do you think we still need above comments ?

Thanks you,

Jaswinder Singh.
