Message

A couple of patches to fix 2 issues with the zbc code:
* A potential NULL pointer dereference in sd_is_zoned(), if that
  function is called when sdkp->device is not yet set (e.g. if an error
  happen early in sd_probe()).
* Make sure that sdkp zone information memory is never leaked.

  scsi: sd: Fix potential NULL pointer dereference
  scsi: sd_zbc: prevent zone information memory leak
