libata: fix handling of port actions in per-dev action mask
libata EH ignores port-wide actions in per-dev action mask. However, device resume requests EH_SOFTRESET using per-dev action mask. Under certain circumstances, this results in not resetting frozen port after resuming which causes failure of all commands. This patch allows port-wide actions to be requested in per-dev action mask. Before EH recovery starts, port-wide actions will be collected. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
