commit: 9716387311c790de381214c03e7f1b72b91a8189 From: Sergei Shtylyov <[email protected]> Date: Thu, 19 Jan 2012 19:09:56 +0300 Subject: pata_legacy: correctly mask recovery field for HT6560B
According to the HT6560H datasheet, the recovery timing field is 4-bit wide, with a value of 0 meaning 16 cycles. Correct obvious thinko in the recovery field mask.
