Sorry, that only took care of one of the two warnings :-) This patch is better. -------------------- drivers/net/usb/asix.c: Fix pointer cast. Stephen Rothwell reports the following new warning: drivers/net/usb/asix.c: In function 'asix_rx_fixup': drivers/net/usb/asix.c:325: warning: cast from pointer to integer of different size drivers/net/usb/asix.c:354: warning: cast from pointer to integer of different size The code just cares about the low alignment bits, so use an "unsigned long" cast instead of one to "u32".
