Date: Fri, 30 Mar 2012 12:58:22 -0700 From: Greg KH <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org, stable@...r.kernel.org Cc: torvalds@...ux-foundation.org, akpm@...ux-foundation.org, alan@...rguk.ukuu.org.uk, Sergei Shtylyov <sshtylyov@...mvista.com>, Jeff Garzik <jgarzik@...hat.com> Subject: [ 060/108] pata_legacy: correctly mask recovery field for HT6560B 3.0-stable review patch. If anyone has any objections, please let me know. ------------------ From: Sergei Shtylyov <sshtylyov@...mvista.com> commit 9716387311c790de381214c03e7f1b72b91a8189 upstream. 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.
