Subject: libata: request PHY speed configuration on SControl access failure
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=db64bcf387aae6c7afad122a529d7d0513d3c5db;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

libata: request PHY speed configuration on SControl access failure

In sata_set_spd_needed(), if SControl read failed, it returned 0 and
skipped PHY speed configuration.  However, if SControl access fails,
it's far more logical to request PHY speed configuration.  Reverse the
logic.
