X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7a31ec3c1ff1ceeb3aebe25e13def5ac4edd5dc4;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[SCSI] st: convert get_location to use st_scsi_kern_execute

This replaces st_do_scsi in get_location (READ_POSITION) with
st_scsi_kern_execute.
