From 5c4fb76af31e9dabcd132a0e69ed3799df1304c3 Mon Sep 17 00:00:00 2001 From: Mark Salyzyn Date: Tue, 17 Jan 2012 12:56:45 -0500 Subject: [PATCH] [SCSI] pm8001: fix lockup on phy_control hard reset. pm8001_phy_control PHY_FUNC_HARD_RESET locks up on second try via smp_phy_control because response HW_EVENT_PHY_START_STATUS fails to complete previous command. The PM8001F_RUN_TIME flag is not treated as a bit, but a state in all readers, yet once we are operational or in the run time state, the flags use a bit-set operation.
