Fixing exposed the fact that improperly ignore the return value of scsi_device_reprobe() in _scsih_reprobe_lun(). Fixing the calling code to deal with the potential error is non-trivial, so for now just WARN_ON(). The handling of scsi_device_reprobe()'s return value refers to _scsih_reprobe_lun() and the following link: https://lore.kernel.org/all/094fdbf57487af4f395238c0525b2a560c8f68f0.1469766027.git.calvinowens@fb.com/ Fixes: f99be43b3024 ("[SCSI] fusion: power pc and miscellaneous bug fixs") Signed-off-by: Zeng Heng <zengheng4@huawei.com> --- drivers/message/fusion/mptsas.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-)
