This patch (commit ID ca9c8a1e in the master branch) causes compile
warnings on all systems that use this driver, for example:
+ ./MAKEALL imx31_litekit
Configuring for imx31_litekit board...
smc911x.c: In function 'smc911x_shutdown':
smc911x.c:130: warning: large integer implicitly truncated to unsigned type
smc911x.c:132: warning: large integer implicitly truncated to unsigned type
smc911x.c:134: warning: large integer implicitly truncated to unsigned type

The problem seems to come from this part of the code:

wher eyou ar epssing long constants (TX_CFG, RX_CFG) into
smc911x_set_mac_csr(), but smc911x_set_mac_csr() is declared
in "drivers/net/smc911x.h" to take an "unsigned character" argument
only:
static u32 smc911x_get_mac_csr(u8 reg)
Please check what's wrong.
Please either provide a fix, or I will have to consider to revert this
patch for the upcoming release.
Thanks.
Best regards,
Wolfgang Denk
