Subject: [SCSI] sym2: Report disabled devices and LUNs more attractively
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=66e8d1cc64e95be78e6138cc88635f7e3108ef58;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

[SCSI] sym2: Report disabled devices and LUNs more attractively

Rather than print a list of targets at driver init time, print each
disabled target as we attempt to scan it.
