ata: pata_artop: remove redundant initialization of pio
pio is initialized and the data is never read, instead it is almost immediately being updated to a new value. Fix this by removing the initialization. Detected by scan-build: "warning: Value stored to 'pio' during its initialization is never read" Fixes: 669a5db411d8 ("[libata] Add a bunch of PATA drivers") Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Tejun Heo <tj@kernel.org>
