Subject: isci: Device reset should request sas_phy_reset(phy, true)
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bc6f387d3156702a0430585b93c04934254c0de1;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

isci: Device reset should request sas_phy_reset(phy, true)

The hard_reset parameter passed to the LLDD in the direct-attached
phy control case allows the LLDD to filter link failure events
while the direct-attached device reset is executing.
