    bsg: fix sysfs link remove warning · 37b40adf
    Stanislaw Gruszka authored
    We create "bsg" link if q->kobj.sd is not NULL, so remove it only
    when the same condition is true.
    
    Fixes:
    
    WARNING: at fs/sysfs/inode.c:323 sysfs_hash_and_remove+0x2b/0x77()
    sysfs: can not remove 'bsg', no directory
