xsysace: Fix dereferencing of cf_id after hd_driveid removal

glikely · bzolnier · commit f0edef8c8b35 · 2009-04-08T14:13:04.000+02:00
Commit 4aaf2fe (xsysace: make it 'struct hd_driveid'-free) converted the cf_id member of 'struct ace_device' from a 'struct hd_driveid' to a u16 array. However, references to the base of the structure were still using the '&' operator. When the address was used with the ata_id_u32() macro, the compiler used the size of the entire array instead of sizeof(u16) to calculate the offset from the base address. This patch removes the use of the '&' operator from all references of cf_id to fix the bug and remove future confusion.
