Subject: tests/srp/rc: Make the SRP tests pass against kernel v5.7
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=1e2c69836342d9c288a6c58bd8cf81d6fb54d866;p=users%2Fsagi%2Fblktests.git

tests/srp/rc: Make the SRP tests pass against kernel v5.7

Linux kernel commit 569334014370 ("scsi: core: Delete scsi_use_blk_mq")
removed the use_blk_mq sysfs attribute. Hence only write into the
use_blk_mq sysfs attribute if it exists.
