Subject: target/spc: Set SPT correctly in Extended INQUIRY Data VPD page
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=27e6772b0d492375621f496a114617bf9c17c8d2;p=linux-beck.git

target/spc: Set SPT correctly in Extended INQUIRY Data VPD page

LIO supports protection types 1,3 so setting a hard-coded SPT=3
is fine for now.
