If anyone has any objections, please let me know. ------------------ From: Wei Yongjun commit 58932e96e438cd78f75e765d7b87ef39d3533d15 upstream. 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.
