Subject: target/pscsi: fix return value check
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=58932e96e438cd78f75e765d7b87ef39d3533d15;p=linux-beck.git

target/pscsi: fix return value check

In case of error, the function scsi_host_lookup() returns NULL
pointer not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.
