ata: libata-sff: use *switch* statement in ata_sff_dev_classify()
In ata_sff_dev_classify(), replace a string of the *if* statements checking the device's class with the *switch* statement that fits better here... While at it, fix the multi-line comment style in the vicinity... Signed-off-by: Sergey Shtylyov <s.shtylyov@omp.ru> Signed-off-by: Damien Le Moal <damien.lemoal@opensource.wdc.com>
