Here, The function pdc_hardware_init always return zero. So it is not
necessary to check its return value.
Fix these checkpatch.pl error:
ERROR: space prohibited after that '~' (ctx:WxW)
+ mask &= ~ (1 << (6 + ATA_SHIFT_UDMA));
ERROR: spaces required around that '?' (ctx:VxW)
+ long pout_required = board_idx? PDC_133_MHZ:PDC_100_MHZ;
ERROR: that open brace { should be on the previous line
+ const struct ata_port_info *ppi[] =
+ { &pdc2027x_port_info[board_idx], NULL };
