Zheyu Ma aafa9f9583 ata: pata_marvell: Check the 'bmdma_addr' beforing reading ... Before detecting the cable type on the dma bar, the driver should check whether the 'bmdma_addr' is zero, which means the adapter does not support DMA, otherwise we will get the following error: [ 5.146634] Bad IO access at port 0x1 (return inb(port)) [ 5.147206] WARNING: CPU: 2 PID: 303 at lib/iomap.c:44 ioread8+0x4a/0x60 [ 5.150856] RIP: 0010:ioread8+0x4a/0x60 [ 5.160238] Call Trace: [ 5.160470] <TASK> [ 5.160674] marvell_cable_detect+0x6e/0xc0 [pata_marvell] [ 5.161728] ata_eh_recover+0x3520/0x6cc0 [ 5.168075] ata_do_eh+0x49/0x3c0 Signed-off-by: Zheyu Ma <zheyuma97@gmail.com> Signed-off-by: Damien Le Moal <damien.lemoal@opensource.wdc.com>		2022-04-22 08:45:06 +09:00
