Hi,

This patch solves the build failure, but with following warnings
CC drivers/ata/pata_scc.o
drivers/ata/pata_scc.c: In function ‘scc_error_handler’:
drivers/ata/pata_scc.c:909: warning: passing argument 3 of
‘ata_bmdma_drive_eh’ from incompatible pointer type

and after that the build fails with

CC [M] drivers/net/spider_net.o
drivers/net/spider_net.c: In function ‘spider_net_release_tx_chain’:
drivers/net/spider_net.c:818: error: ‘dev’ undeclared (first use in this
function)
drivers/net/spider_net.c:818: error: (Each undeclared identifier is
reported only once
drivers/net/spider_net.c:818: error: for each function it appears in.)
drivers/net/spider_net.c: In function ‘spider_net_xmit’:
drivers/net/spider_net.c:922: error: ‘dev’ undeclared (first use in this
function)
drivers/net/spider_net.c: In function ‘spider_net_pass_skb_up’:
drivers/net/spider_net.c:1018: error: ‘dev’ undeclared (first use in
this function)
drivers/net/spider_net.c: In function ‘spider_net_decode_one_descr’:
drivers/net/spider_net.c:1215: error: ‘dev’ undeclared (first use in
this function)
make[2]: *** [drivers/net/spider_net.o] Error 1
make[1]: *** [drivers/net] Error 2
make: *** [drivers] Error 2
