ARM: ixp4xx: use normal prototype for {read,write}s{b,w,l}
ixp4xx defines the arguments to its __indirect_writesb() and other functions as pointers to fixed-size data. This is not necessarily wrong, and it works most of the time, but it causes warnings in at least one driver: drivers/net/ethernet/smsc/smc91x.c: In function 'smc_rcv': drivers/net/ethernet/smsc/smc91x.c:495:21: error: passing argument 2 of '__indirect_readsw' from incompatible pointer type [-Werror=incompatible-pointer-types] SMC_PULL_DATA(lp, data, packet_len - 4); All other definitions of the same functions pass void pointers, so doing the same here avoids the warnings. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Krzysztof Halasa <khalasa@piap.pl>
